Abstract : A feed-forward amplifier in which samples of the input and output signals of a main amplifier are adjusted in amplitude and algebraically combined to produce a sample of the error introduced into the output signal by distortion and noise in the main amplifier. This error sample is amplified to produce a correction signal by a subsidiary amplifier which itself introduces noise and distortion. The correction signal is algebraically combined with the output signal of the main amplifier and a fraction of the resultant output signal is fed back to the input of the subsidiary amplifier to render the output signal substantially free of error caused by either of the main and the subsidiary amplifiers.
