Express closed loop voltage gain (AF) in terms of open loop gain (A) and feedback circuit gain (B)?
A. AF = A/AB
B. AF = 1+ (A/AB)
C. AF = A/(1+AB)
D. AF = AB/(1+A)
Answer:A
Express closed loop voltage gain (AF) in terms of open loop gain (A) and feedback circuit gain (B)?
A. AF = A/AB B. AF = 1+ (A/AB) C. AF = A/(1+AB) D. AF = AB/(1+A)
Explanation: The closed loop voltage gain in terms of open loop gain and feedback circuit gain is expressed as AF = A/(1+AB).
