Compute the voltage gain with feedback, Physics

Assignment Help:

Q. The voltage increase of an amplifier without feedback is 100. If negative feedback is functioned with feedback fraction 0.1, compute the voltage gain with feedback.

A F      = A / 1 + A β

= 100 / 1 + 100 X 1/10

= 100 / 11 = 9.09
