Consequently, even a casual disturbanceat the input will appear in the amplified form in theoutput. There is a strong tendency in Amplifiers to in-troduce hum due to sudden temperature changes or strayelectric and magnetic fields. Therefore, every high gainamplifier tends to give noise along with signal in itsoutput. The noise in the output of an amplifier is unde-sirable and must be kept to as small a level as noise level in Amplifiers can be reduced con-siderably by the use of Negative Feedback by in-jecting a fraction of output in phase opposition to theinput signal.
