A negative feedback amplifier has a close-loop gain af100


A negative feedback amplifier has a close-loop gain Af=100 and an open-loop gain A=105. What is the feedback factor ?? If a manufacturing error results in a reduction of A to 103, what close-loop gain results? What is the percentage change of Af corresponding to this factor of 100 reduction of A?
