So you have access to the mains whilst you are diving?…..or you mean you have a generator on the boat which gives you the 230VAC, 50Hz sinusoidal power source? I.e., what is your power source?…85-265VAC or 230VAC, etc etc, and if off an inverter, is it sinusoidal or square wave? How long is the cable from the lighting power (...)
A quite simple method: Using a frequency variable sinusoidal generator (with a series resistor such that R>>wL and a decoupling C), and an oscilloscope or an AC voltmeter, measure the resonant frequency of the inductor with a fixed capacitor (frequency that gives maximum voltage in the parallel LC). With current flowing across the inductor (using
High I need a sinusoidal ef power generator circuit operating in class-E (for high efficiency) in the range of 35-100KHz 5-30W or so. just a power oscillator, not a generator followed by an audio amplifier. Any propositions?
Hello I have a sinusoidal signal generator connected in series with a toroidal choke and the choke is connected to the oscilloscope to the ground. As I vary the frequency of the generator I notice dips and peaks of the sinusoidal waveform on the scope. I find the maximum peak which is at a specific frequency. Then I reduce (...)
If i told you that you could get a strand of insulated wire (not coiled), make 50KHz sinusoidal current flow in it from a generator..........and then hook a resonant inductive coupler over the strand of wire, and couple 50W out of the strand of wire, and use it to light a LED luminaire with the 50W, would you say that this was feasible? .....t
In general a buffer, able to drive the capacitance of the cable is required. The choice will depends from factor like frequency, type of signal (sinusoidal, squarewave, etc.), noise/allowed jitter, etc. A microstrip (or a stripline) is required to route the signal from generator to the buffer and from the buffer to the cable, in order to avoid impe
Hello Guys I want to write the code in which I want to calculate the initial point from where I can start in a sinusoidal signal. Actually the problem is that I have provided a sinusoidal signal from the function generator to the ADC of the microcontroller which is than converted to the digital value , now since the ADC of the (...)
you need a distortion meter, something like this : with a pure sinusoidal generator like this : two modules can be found sometimes used on ebay. also
Yes, it is the task and the goal that a harmonic oscillator produces a sinusoidal output. However, because of the (small) non-linearity that is absolutely necessary for proper operation the output can be only "quasi-sinusoidal" (sinus with distortions). The classical relaxation generator produces an exponential shaped signal across a (...)
This device generates frequencies in range of 0,2 ? 20000Hz. The frequencies can be changed in 6 ranges, in each of them there is a possibility of continuous regulation. Generating sinusoidal, rectangle, triangle and
hi all out an electronics student and doing my project. i am using pic 18f4431 microcontroller to produce two sinusoidal pulse width modulated signals that i will use to control my H bridge so that i can construct a simple inverter. i have written some code using ccs but on simulating on proteus i am not getting the required output. the
Hi Marius, instead of generate sinusoidal waves with PWM, DAC or an analog waveform generator, you can use your microcontroller (or other digital circuit) for generate a square wave at f0 and f1. Then, filter the square-wave FSK with a low-pass or passband filter. That filter has to pass the band centered at about 20 KHz, and the lower band that
You can use the sinusoidal wave generator (sine) which has only one connection point (signal), the other end is already connected to the gnd. The second solution is to use a VSINE component which is exactly as your first picture, you can find it in the components (opamp icon under the arrow, second icon from the top and there press letter P to pick
Its true, anti-parallel Schottky diodes will get lower even harmonics, but this is valid only if at the input is an ideal sinusoidal signal (fundamental only, free of harmonics). If there are already even harmonics at the pair diodes input, even harmonics will have consistent amplitude at the output (as in our case where the MMIC is in saturated r
In MATLAB, there are two types of "Sine Wave" generator (see figure below). One can be found in Simulink library, and another one can be found in Signal Processing Blockset (SPB). When the "Output complexity parameter" of SPB "Sine Wave" block to Complex, it will generate complex sinusoidal signal. What is the different between the sinewave g
Hello Everyone, Wish You All A Happy New Year. I have a simple problem that I am trying to simulate in Microwave Office. Since, I am a novice user of MWO and in general AWR, I appreciate some help in this regards. The problem goes likes this: A DDS based Chirp generator output (FMCW Liner Chirp) is mixed with a sinusoidal signal. How do I model
Use the PWM output, change the duty-cycle with sinusoidal law, then feed the PWM to the bridge switch and put a output LC filter in order to retain only the 1st harmonic. About the sinusoidal modulation of the duty cycle you can use a look-up table stored inside the micro. Just a idea. Bye Pow
Hello, I want to do real time FFT of a 1kHz sinusoidal signal which is coming from signal generator with the help of TMS320C6713 DSP kit and see the frequency spectrum of the signal on some graph on computer screen. How should I do that? Thanks & regards, Arun
You will use a small-signal sine-wave generator of a fixed peak-to-peak voltage and a specified frequency. Then, you will measure the current flowing through the capacitor, which is also a sinusoidal in waveform. And, you will calculate C using the equation i = jwc * v, where j means a phase shift of pi / 2.
i need a waveform generator, which is getting digital input from MCU and output is to be a pure sinusoidal signal of desired frequency. can anyone provide me a circuit for it
