Question: A negative feedback amplifier has a closed loop gain of Af = 1 0 0 and open loop gain of A = 1 0 5

A negative feedback amplifier has a closed loop gain of Af=100 and open loop gain of A=105. What is the feedback factor ? If a manufacturing error results in a reduction of A to 103, what closed loo gain results? What is the percentage change in Af corresponding to this factor of 100 reduction in A?2. Repeat (1) for A=100
