WebA square wave is approximated by the sum of harmonics. In this particular SPICE simulation, I’ve summed the 1st, 3rd, 5th, 7th, and 9th harmonic voltage sources in series for a total of five AC voltage sources. The fundamental frequency is 50 Hz and each harmonic is, of course, an integer multiple of that frequency. WebJurek wrote, "My first question - how to make such a "noisy" signal?" If you want to simulate a 100 kHz switching signal, but you don't have a model for the part that actually generates it, I would suggest using either a PULSE voltage source with a 100 kHz switching rate. By changing the rise and fall times and pulsewidths, you can vary the harmonic content. new mine in hotazel

WebOct 28, 2013 · With the square generator, the integrator is initialized in positive saturation because the initial input voltage is negative. But the square wave isn't exactly symmetrical (due to a small finite rise and fall time), causing a slow drift and negative clipping. You can change the behaviour by adjusting VPULSE and .tran parameters.
