For how many values of the impulse response, a perfect match is present between h(n) and hd(n)?
A. L
B. M+N+1
C. 2L-M-N-1
D. All of the mentioned
Answer:A
For how many values of the impulse response, a perfect match is present between h(n) and hd(n)?
A. L B. M+N+1 C. 2L-M-N-1 D. All of the mentioned
Explanation: We obtain a perfect match between h(n) and the desired response hd(n) for the first L values of the impulse response and we also know that L=M+N+1.
