Which of the following gives the equation for envelope delay?
A. dϴ(ω)/dω
B. ϴ(ω)
C. -dϴ(ω)/dω
D. -ϴ(ω)
Answer:A
Which of the following gives the equation for envelope delay?
A. dϴ(ω)/dω B. ϴ(ω) C. -dϴ(ω)/dω D. -ϴ(ω)
Explanation: Instead of dealing with the phase response ϴ(ω), it is more convenient to deal with the envelope delay as a function of frequency, which is
