Isolating harmonics with band-pass filter

  1. Jun 25, 2012 #1
    If electric waveforms such as square waves, sawtooth waves, and triangle waves are really no more than sine waves with added harmonics, one could run such a wave through a bandpass filter (or several) and isolate one of the harmonics as a sine wave?

    Yes!!! You need good and sharp BPF though. Also, it's all relative, it's all about how low you want to suppress the unwanted harmonics.
