Many audio transmission systems distort the transmitted signal in a complex but predictable manner. This distortion may be removed by applying a compensatory predistortion to the signal before transmission. A method of predistortion using a -feedforward loop- circuit is described, with an analysis of its linear behavior and stability. Applications are given to FM multiplex broadcasting with a narrow sideband spread, and to the class D mode of power amplification.
