What is the number of filter coefficients that specify the frequency response for h(n) anti-symmetric?
A. (M-1)/2 when M is even and M/2 when M is odd
B. (M-1)/2 when M is odd and M/2 when M is even
C. (M+1)/2 when M is even and M/2 when M is odd
D. (M+1)/2 when M is odd and M/2 when M is even
Answer:A
What is the number of filter coefficients that specify the frequency response for h(n) anti-symmetric?
A. (M-1)/2 when M is even and M/2 when M is odd B. (M-1)/2 when M is odd and M/2 when M is even C. (M+1)/2 when M is even and M/2 when M is odd D. (M+1)/2 when M is odd and M/2 when M is even
Explanation: We know that, for a anti-symmetric h(n) h(M-1/2)=0 and thus the number of filter coefficients that specify the frequency response is (M-1)/2 when M is odd and M/2 when M is even.
