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.
