ABSTRACT:
A feed-forward system for reducing the distortion products from a device such as an amplifier, wherein samples of the distortion products from the output of the device in one or more frequency bands whose bandwidths are less than that of the device are extracted, adjusted in amplitude and phase and subtractively combined with the device output to produce a system output in which distortion in the frequency bands is reduced.
