Electronic amplifier with feedback has part of output signal back to linearize frequency characteristic, reduce distortion; not all, but at least one output stage has feedback line to amplifier

摘要

The amplifier has several parallel controled output stages and part of the output signal is fed back to the amplifier to linearize the frequency characteristic and reduce the distortion caused by the amplifier. Not all, but at least one of the output stages has a feedback line to the amplifier.
