Find the voltage gain after feedback, Physics

Assignment Help:

Q. When there is no feedback, the gain of the amplifier is 100. If 5% of the output voltage is fed back into the input through a negative network, find the voltage gain after feedback.

     A F = A / 1 + A β

                        = 100 / 1 + 100 X 5/100 = 100 / 6

= 16.66
