Compute the feedback ratio, Physics

Assignment Help:

Q. When the negative feedback is practical to an amplifier of gain 50 the gain falls to 25.  Compute the feedback ratio?

Af = A / 1 + Aβ

25 = 50 / 1 + 50 β

1 = 2 / 1 + 50 β

1 + 50 β = 2                             (i.e) 50 β = 1

β = 1 /50 = 0.02
