Abstract
The present invention reduces the distortion components produced from high power level mixing through a set of adaptive cancelling circuits which utilize a low power level mixing of the same signals to provide a signal which is adaptively cancelled with a signal representative of the high power level signal including distortion to provide an output signal which comprises substantially only the distortion components found in the high power level signal. These distortion components are then adaptively cancelled or combined with the high power level signal including distortion to provide an output signal which comprises the primary signal and insignificant levels of noise and distortion.
