If the phase ϴ(ω) of the system is linear, then the group delay of the system:
A. Increases with frequency of signal
B. Constant
C. Decreases with frequency of signal
D. Independent of frequency of signal
Answer:A
If the phase ϴ(ω) of the system is linear, then the group delay of the system:
A. Increases with frequency of signal B. Constant C. Decreases with frequency of signal D. Independent of frequency of signal
Explanation: We know that the group delay of the system with phase ϴ(ω) is defined as
