Hello G, I have uploaded an example with the A-device "Modulate2" to the TEMP-folder. Modulate2_DSBSC.asc This example runs 1000 times faster than any version with SPICE models of real ICs. OK, when

Yes Helmut. I've seen the modulator. But does it suppress the carrier? To my surprise I can not find a LTC multiplier. There is one, the 4151, but it is to complex to us it on sucha trivial purpose.

Hello, You can run the FFT to check that the carrier is suppressed. Make sure that your time frame contains an integer number of cycles of the modulated signal. If the waveform window is active, then

Vlad, I added one more circuit. And I asked the question. See my other letter! And see the file four_ways_to_determine_the_inductance.zip. Bordodynov. 16.08.2016, 10:35, "Vlad imbvlad@...

edge, so it is not a strictly linear ramp, but it's close. So, the specified Trise or Tfall works for approximately the 0% to 97% or 99% points (on the cases I tried -- it depends on risetime). But

Thank you Jim. Just remembered '78 when using a SAR DAC achieve same result. Hmmm... it it a long time.used it in NDT on Nuke Reactors :) How will I display such a signal on the simulator ? G. To:

Hello Vlad. I think not the average, and calculate the amplitude of the first harmonic. I made a parallel Fourier analysis. Look at the first harmonic and what I counted. The values are the same, with

Hello after a short delay drops sharply to a low voltage and holds for a short delay, then charges exponentially to a an intermediate voltage and holds for a short delay, then finally drops sharply to

Just a multiplier with no offset. One input is carrier, other is 1200Hz sine. You then have your double sideband suppressed carrier signal. Jim James Wagner Oregon Research Electronics

Hello Bordodynov You are doing an average of the waveform. For simplicity, let's assume V(x) is a 1V sine, just like the reference. Then: V(sin) = idt{ Vref * V(x) - delay [ Vref * V(x), 1/f ] } * 2 *

Here I really got stuck. I need a signal generator in the simulator to create a Double Side Band Suppressed Carrier Modulated by 1200HZ. Can any one point me in the right direction? G.

Hello. I investigated the current transformer ratio as a function of the inductance of the secondary winding. The transformer includes a non-linear core. As a result, the inductance depends on the

Thank you Andy. I do know these "facts" but simulator programmers have a tendencyto "improve" on the agreed parameters. It is always wise to ask what the programmer thinks in this respect. G. To:

Hello, There are examples with bridge rectifiers (schematic, symbol, models) with a library of models. Some models in this library file are similar(voltage, current) to the asked model.
