can anybody explain how to solve the following please
A voltage amplifier with an open loop gain of 10^4 has applied to it in turn 1% negative feedback and 5% negative feedback .
For each case calculate the effect on:
Gain magnitude
Gain stability if Av varies by ± 6%
Bandwidth assuming B(Av) =40KHz
Signal to noise ratio with feedback if S/N=20dB.
many thanks
