for the Nominal case (TT) it has a strange value, instead in the others corners it seems quite good. ??? The numbers show higher PSRR (better) for TT. - - - Updated - - - Higher than expected is a bit different from failure. Everything is just simulation, it's easy to "look into" the
What is Convert.ToBoolean(date) expected to mean? Seems useless.
Are there any more specifications? What is the minimum load value allowed on the output? Are you limited to one active device per stage? What is the maximum output swing expected? Maximum output distortion allowed? Frequency bandwidth of operation? - - - Updated - - - It would be much easier if
Hello, Hopefully this is posted in the right area. I'm trying to model the current of the device which is captured by one of the last lines of this code: (I(p,n) <+ ddt(polar);) // VerilogA for tech_support3, test, veriloga `include "constants.vams" `include "disciplines.vams" `define M_PI 3.14159 module test(p,n); inou
I like to run simulations to see what behavior can be expected. This schematic shows approximately how a flyback converter boosts 30V to 96V, 300W. of the 1:1 winding ratio, it needs an unusually long duty cycle. The 12 uH primary value was determined by hit-and-miss exper
You'll need RF transistors to achieve power gain at 100 MHz. A 2 N3904 zener diode can be expected to generate wideband current noise, but it needs to operate on a much lower load resistor for almost frequency independent output. You find much literature about RF noise generators, e.g.
Makes no sense: cli(); int temp = profile.moved_steps; sei(); process(profile.moved_steps); did you mean process(temp); I don't see a particular fault. I guess you are seeing the correct actual value, but probably from a time different than expected.
The shown schematic is expected to work. Possible reasons for the observed problem: - MOSFET defective - wrong MOSFET pin assignment I guess, your actual schematic has an additional signal path to turn the MOSFET on. May be it's generating an unwanted voltage across R1.
The amplifiers can be expected to have |S11| < 1, respectively positive dB value of return loss, respectively negative dB value of reflection factor. Surely not negative return loss dB value.
i face problem with simulation in proteus i got wrong output not the expected from the written program but i dont know why ?! while(1){ start : temp = temp_sensor_func(); // call temp sensor function dtostrf(temp, 1, 2, buffer); //convert temp value from double to char to display on LCD and transmit with Uart lcd_print(&Lcd , buf
Although Power Spectral Density (PSD) of EMG signals ranges from 10 to 500Hz most is from 20 to 250Hz. The lower end filter of 70Hz may or may not be ideal. 70Hz is useful for some EMG sources but a lower value has a wider application. The upper range should match your expected PSD of 250 to 500Hz. Since the PSD is asymmetrical the mean nois
I see different values from 0.25 to 1.85 when I connect 40W bulb. What do the numbers mean, Irms A? What's the expected value? How do you calculate AC current from instantaneous sensor output voltage?
The second option is just a blind attempt of producing the output according to the known behaviour of the plant, but do not perform any correction of actual value of output, which in real world could differ from the value expected due to many reasons do not predicted on the ideal plant model, which, no matter how good the model, in certain (...)
I expected a value of some floating point type, but I am always getting 0 instead. Yes, 100 % expectable. You may want to review a C text book about automatic type conversion involved with arithmetic expressions. In this case, language rules require that an integer division is performed and then the quotient converted to float. T
Is "Read the manual" asking too much? For the said UT33A, the AC measurement is specified as Displays effective value of sine wave (mean value response) That could be expected for a non "true rms meter", it's measuring averaged rectified value, result is corrected to be equal with rms for sine voltage. Example, average (...)
The half-bridge applies 12 V peak-to-peak, so 6 V peak. The secondary will receive 6*(220/9.5) = 140 V peak. Since the DVM is calibrated for sine wave the 74 V reading is not unreasonable even if a little lower than expected. If you can't get a true RMS meter, half wave rectify and filter the output, this will give you the true peak value. Accor
Once you have enough memory, as FvM mentioned, the load factor would interfere on the generated output, therefore in my oppinion you should consider storing sinewave tables for different maximum duty-cycles, in order to allow feedback control for compensation of deviations from the expected value at each point of the curve. In addition, as c_mitra
beyond these voltages what will happen to the transformer? In some poor designs where the transformer is sized to operate close to its nominal power rating capacity, a few drop voltage is expected due to losses, therefore if it is the case, it may be expectable a small increase in the output voltage value.
What kind of value should be expected realistically
Hi! The circuit below is not functioning as I'd hoped/expected. This is an experiment making a milli ohmeter, that is the purpose of this circuit; I was unable to breadboard it, or simulate a couple of the ICs, so I just made a prototype to see what would happen, therefore it's very rough and ready. Are there any obvious mistakes in the de
I expect Ib to be Ic/hFE (while its much lesser than this value) because bjt is clearly in active region with Vec=3V When you do not follow design guidelines for normal switch non-linear operation, you can expect unusual results. The BJT has operated as expected because your base bias current far exceeds your load
According to the guideline bellow, the expected MTBF of a single LED component submitted to standard environmental conditions is something near or even superior to the value that you gave above: This is really a considerable lifecycle, however we must keep in mind tha
Depending on if you selected a higher voltage scale, it is expected a more significant effect of the measurement error due to intrinsic inaccuracy of the circuit.
This inverter probably was designed to operate with a minimal load so that it is expected to drop a few the output voltage. Make a test to check if the 285v decreases with a load of about 10% of the rated value. Is this voltage obtained using a peak or rms scale ?
How to read MCP3302 using SPI ? I have to use CH0 of MCP3302 (single ended mode) Please algorithm or C code to read the adc value. It uses SPI. I am using PIC18F46K22. I will use Software SPI. - - - Updated - - - I have written this code but it is not working as expected. Datasheet page no. 24 I ha
Dear Sirs, I simulate a simple capacitor with plates of 4x2 mm and 5um of dielectric (dielectric constant=3.8). The 2-port PI with Shunt RC and Shunt RC model give me a correct value of 54 pf but R is 22987 Ohm. Why R is so low? I expected a more high value. What is R in Shunt RC model? Thanks Ettore.
Hi Everyone, Just wanted to ask experienced antenna engineers, what is the expected sidelobe level, as i've designed a 4-patch antenna array with 10.5dB realised gain, but sidelobe levels of 2.5dB. Do you think this is acceptable at 12-13 GHz frequency? If not, can you suggest some ways to reduce the sidelobe level in array
Hello everyone, I designed constant current generator with LM334 IC but it doesn't work as I expected. I need a current that must not exceed 0.95mA. My load is getting smaller with time and current is increasing, but must not exceed 0.95mA. I am using circuit from page 8 in this datasheet and
On comparing the code with the waveform, I find that the behaviour is as expected. 1. You must understand that when a signal goes high, this high value is checked at the next rising edge of clock. So stall goes high at 1 rising edge, this 1 will be checked at the next rising edge. 2. So if you want PC_reg to stall at 13, you must generate stall 1
what is you expected RPM and how long a time period are you measuring over? e.g. if the RPM is low (say a few revs a second) and you measure over a too short time period (say half a second) the counted revs will vary in RPM value depending on the number of counts in the time slot
Compare DSO result with code emulation or expected results.
Hi, unfortunately it is ADC dependent and therefore you have to look into the datasheet. Often there is an equation for the expected digital output value depending on input voltage and reference voltage. A differential input is not necessary +/- input voltage, sometimes it is used for compensating ground bounce (ADS8320). A reference voltage
Does anyone know by how much does the width and length of the CMOS on 22nm technology vary by. I know its FinFET so the Width issue might be different, but I just need to know the normal change between the expected value, an answer at 3 sigma( That is the max variation). Thank You!
Hi, My project is a simple light dimmer.I connected a port to AN1. adc values are given to pwm1.I am getting only half of the expected frequcy. pic12f1501 is my controller.following is the code that i used. void main() { TRISA2=0; TRISA3=1; OSCCON=0xF3; OSCSTAT=0x10; adc_init(); T2
Depends on the intended inductance value which wasn't mentioned. Generally air core inductors have an extended stray field and must be expected to generate unwanted interferences in the vicinity. Eddy currents may cause additional losses, larger number of turns for same inductance involves increased series resistance. In case of doubt mostly disadv
I presume, you have already heard how inductance, frequency and inductive resistance (reactance) are related. The other question is, if your inductor is so small and the core permeabiliy is so low that a value of about 6.5 nH can be expected. Or if it's just an erroneous simulation setup. (The
As we have no idea what the expected switching rate/frequency is in your application, it is kind of hard to suggest a value, but a simple low pass RC filter on the input should do it - if the wiring is going out to mechanical switches/relays, you should probably have some filtering and/or transorbs or clamping diodes on the inputs anyway to prote
Why this code not working as expected? According to code, If + button is pressed the adc variable value should go upto 255 and stop. If decrement button is pressed it should go to min 0 and stop. adc variable is multiplied by 2 and written to POT. So, for 255 steps I should get 510 max adc value from channel 3. It is incrementing beyond range.
I want to know what does it means the expected value of a signal X times the conjugate transpose of itself. X is a matrix with complex entries. 99289
Why not read the compiler manual? Please consider that when passing a 16-bit variable, the expected maximum pulse width value is 4*period. This is essentially a PIC hardware thing and not particularly related to CCS C. The CCS specific point is to scale 8-bit and 16-bit variables differently in the built-in function. Writes the 10-bit val
Hi guys, I've been doing multitone Harmonic Balance simulation with ADS. I've been using "labels" to monitor the evolution of the power amplitude of the various tones between the devices. I've noticed that the value of the power amplitude shown is always a little bit higher than the expected, and after some controls I've found out the reason: it wa
For the below circuit, I have placed multimeter +ve probe at 'B' wrt GND and measures 4V against the expected value of 0V. Hence I have terminated the 'B' end with 10K to GND temporarily before taking the measurement and reads 0V. Why this happens? What happens to the anode of D2 while I connect a multimeter to 'B' end wrt GND ? I have

Hello I have a question regarding naming conventions in layout and schemtics. Suppose I use vdd! and vss! to represent in my layout for vdd and gnd. When i run a testbench simulation, i assign the local value vdd! to the master value vdd. But i still see that my ouput is not as expected. Could anyone help me with this? Thanks BB
Hi, I've been using a PIC16F88 to control 7 segment displays, LCD controllers and a BCD all without problem, but I'm struggling to understand the ADC. The setup: I have setup the PIC to read a value from a 10k trim pot linked to the 5v supply that feeds the PIC. The PIC is using the internal clock and setup to run at 4Mhz. The ADC is setup t
I am writting 8 bits counter value (16 values) to a binary file and read it back to 128 bits variable. Input Data: 0x00, 0x01 ..... 0x0f Output Data (expected): 0x00010203....0f (128 bits) My Code is here module read_mem; integer fin; integer fout; reg data8; reg data128; integer idx; integer
I'm not familiar with MikroC details (and don't intend to get bothered by it more than necessary). In general C and PIC terms, we can say - a parameter, that is expected to change it's value after function call, can be only passed by reference (as a pointer) rather than by value - to pass a reference to an individual SFR bit, a bit (...)
