An all-pass network imparts only
A. Negative phase to the input
B. Positive phase to the input
C. 90 degree phase shift to the input
D. 180 degree phase shift to the input
Answer:D
An all-pass network imparts only
A. Negative phase to the input B. Positive phase to the input C. 90 degree phase shift to the input D. 180 degree phase shift to the input
Explanation: An all-pass network is the network that is the combination of the minimum and non-minimum phase systems and have the magnitude 1 for all frequencies and imparts only 180 degree phase shift.
