The voltage gain magnitude of all-pass filter is
A. Zero
B. One
C. Infinity
D. None of the mentioned
Answer:A
The voltage gain magnitude of all-pass filter is
A. Zero B. One C. Infinity D. None of the mentioned
Explanation: The magnitude of voltage gain of all-pass filter |VO /Vin| = √(1+(2π/RC)2) / √(1+(2 π/RC)2) =1. 13. What happens if the position of R and C are interchanged in the below circuit diagram?
