Negative feedback is a process that reduces the gain of an amplifier in order to reduce distortion. It works by feeding a portion of the output signal back to the input, so that it cancels out some of the original signal. This can reduce harmonic distortion, as it reduces the amount of signal energy that is being amplified, which in turn reduces the amount of distortion created by nonlinearities in the amplifier circuit.
