Amplitude distortion in which the output and input signal envelopes are disproportionate (in the absence of spurious frequencies).

CONT

The effects of multipath distortion are dramatically illustrated when one listens to or watches colour TV as an airplane passes between the transmitter and the receiver. Here either noise or distortion is heard from the FM receiver and the colours wash out on the TV set. A similar effect, called linear distortion is observed on wire communications systems.
