first i just know A VERY LITTLE basics of OrCad Capture But my course project is about this circuit 134217 That's (Sound sensitive dancing leds ) Doing it On breadboard and simulating it on orCAD after some research i found out that orCAD can't simulate LEDs , mic and transistor and what i need for the presentation is
first, there are (and I have designed & seen installed to production) precision voltage references that are rated over at least -55C to 125C. What I do not see, is a quantitative spec on "stable". This of course varies by the application; a power supply reference is good at 1% but if you imagine you're going to make a 16-bit data acquisition lineup
Meaning the priority is decided in your ISR depending on which flag you check first. The flags are set regardless of whether GIE is enabled or not, all GIE does is determine if the program jumps to the ISR. If you are polling the flags you can still use the interrupt system without an ISR but of course it tends to make the program less responsive
first stage output/second stage input node is high impedance, too. Diode connected? I don't see a diode connected MOSFET. The compensation network will of course reduce the OTA output impedance, as well as the input impedance of the second stage.
... You have also unbalanced output stage and first stage which can produce additional offset. I think this shouldn't matter at gain=1 feedback (and no gate input current, of course).
At first sight, the code function can shortened as bcd = code, because it simply performs a bit-by-bit copy. But what did you want to achieve?
Your first question is malformed. As to your second, yes; this is exactly how CMOS-SOI RF switches are made. There are of course constraints to the application. You could also make a DC switch this way if you employed a means of applying a gate charge across an isolation barrier and stored it across G-{S,B}.
I can't remember exactly when I first used the DAC0808 but I think it must have been around 30 years ago so advances in technology means almost all new devices will surpass it in performance. It still works of course but there are now hundreds of better alternatives including many with direct voltage output if that's what you need. Brian.
I have interfaced MCP7940M with AVR. I know working of I2C where in case of RTC write we use following sequence: 1. Start 2. Slave address+Write bit 3. Register address 4. Register data 5. Stop And of course after each byte there is ACK or NACK But actual confusion is in RTC read Definitely first two steps will be as it is only ther
I am creating a second order delta sigma modulator for a fractional n pll. first I created the first order one. It worked ok when I removed the output flip flop that had to act as a comparator. Of course there's some sort of comparator glue logic. However it is combinational circuit. I wrote a code in matlab and it worked fine, designed the (...)
The output of a first order filter can be most simply predicted in time domain, it's just a succession of exponential waves. The first derivative will be always discontinuous, so it can be clearly distinguished from a sine.
You should start with loading A with the first value and add the next 6 before you divide by 7. When you do what you do in your example you start with an unknown A register adding the first value. You can of course clear the A register or load it with 0 before you start the adding(with 7 values. Remember to check that the 7 values does (...)
If you want it to saturate at MAX_Range then just change the first line to: if (I >= MAX_Range) then I <= MAX_Range; Of course once it reaches MAX_Range it will never change, unless you add code to reset I to something else. - - - Updated - - - I also don't understand your usage of resiz
The assumption in your first post is wrong, the voltage is of course reduced for k < 1. There a different methods to describe coupled inductors and it's important to clarify which model you are using. A straightforward model, that's often used in EM analysis of arbitrary conductor geometries is an impedance matrix: Zij = Rij + ωLij V
Before a base current can exist a proper base-to-emitter voltage is required - as a first biasing condition. Of course. It is assumed that there is enough voltage to create the base current. I do not want to argue whether a current causes a voltage or whether a voltage causes a current.
You have too many threads about your noisy printer room. In your first thread you were told that using sound absorbent material for walls, ceiling and floor will reduce the average sound level. Of course earplugs should be used by workers but I recommended noise cancelling headphones.
Gravitational attraction causes the deceleration. Astrophysicists have debated whether the universe will slow its expansion and collapse eventually. Latest evidence says it will continue to expand forever. This is similar to the concept of escape velocity. At Earth's surface it is 7 miles per second. For the universe it could have been a large per
HFSS doesn't know where your Penrose polyhedron starts (of course there is some first vertex, but you can't be sure yourself). Every operation is performed around the coordinates origin. Therefore, create local coordinate system attached to the object first. But to avoid you project becoming a garbage pile, create local coordinates only (...)
A lot of what can be done and how depends upon what software you have. What PCB software and what Gerber software. Of course, it goes without saying that this should be done in the PCB CAD file first but sometimes they are not always available with legacy data.
i am little bit late to the course,my question is how making the vehicle to get into almost desired speed equation is u=ke. e=r-y if on speed of vehicle is 30 reference speed is 70 km/hr. for the first time we get e=40 as feedback.and further this 40 is carried out in what way in order to get the vehicle to 70 km/hr speed.please help m
