Vedclass · Answer

(B) Negative feedback in an amplifier is a technique where a portion of the output signal is fed back to the input in phase opposition to the original input signal.This process reduces the overall gain of the amplifier but provides several benefits.Specifically,negative feedback significantly reduces the noise and distortion introduced by the amplifier circuitry itself.It also increases the bandwidth and stabilizes the gain against variations in temperature or component aging.Therefore,the correct effect of negative feedback is the reduction of both noise and distortion.
