WebPulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) or Pulse Time Modulation (PTM) is ... WebThe preferred method of demodulation is first to convert the PWM signal to PAM, and then reconstruct with a lowpass filter. Conversion to PAM can be effected with an integrate-and-hold function. Unlike PWM, PAM does not exhibit multiple sidebands around the clock frequency. Thus (aliasing) distortion is not going to increase with depth of ...
