WebHarmonics. Any complex waveform can be represented by a series of sine and cosine waves that make up its Fourier series or Fourier spectrum. If a transmitter produces a pure sine wave output signal, then only carrier frequency F will appear in the spectrum. But if the signal is distorted in any way, no matter how little, then harmonics appear.
