  • Pop Quiz Answer: The 120Hz signal comes from the full-wave, center tapped rectifier. Since each diode conducts during half of the incoming 60Hz waveform (one on the positive half cycle, one on the negative half-cycle), you get double the incoming frequency on the output of the rectifier.
    BTW, great beginner tutorial.

No public wish lists :(
