Positive feedback increases the gain of an amplifier.NEGATIVE (DEGENERATIVE) FEEDBACK is provided when the feedback signal is 180º outof phase with the input signal. Negative feedback decreases the gain of an amplifier but improves fidelityand may increase the frequency response of the amplifier.1-37
