Feedback is used to reduce the

Feedback is used to reduce the distortion appearing at the load by a factor of 10.

a. Determine the rms value of the load voltage F3 .

b. What is the over-all voltage transmittance Avo ? Note that there must be a net sign reversal in the internal amplifier.

c. Determine the values of A'vo and 0. (The value of a can be taken as unity.)

d. The last stage of the amplifier, which is designed for maximum power output, has a voltage amplification A2 = 1. The source AiEi represents one or more cascaded voltage-amplifier stages with an amplification of 100 per stage. How many voltageamplifier stages are required?
