AMPLIFIER WITH SUBSTANTIALLY ZERO DISTORTION PRODUCTS

摘要

An amplifier with substantially zero distortion products is disclosed. A circuit is provided that independently compares the signals in the amplifier output with all the signals provided by the amplifier input source and discriminates between the original signals (fundamentals) and non-original signals (distortion product, spurious signals, and noise, etc.) present in the output terminals of the amplifier or network. Having discriminated and isolated the nonoriginal signals these are then re-inserted back into the amplifier in such phase that provides cancellation of the internally generated products.
