Distortion

  • Distortion is due to non-linearity
  • Harmonic distortion is where integer multiples of the input frequency occur
  • Intermodulation distortion is where two signal components multiply together to make new ones
  • Every amplifier has some non-linearity;  good design and operation within the intended power input (drive) / output range, i.e., not overdriving it minimises distortion
  • Distortion manifests itself as interference and splatter
