Which of the following is equal to the value of H(k+α)?
A. H*(M-k+α)
B. H*(M+k+α)
C. H*(M+k-α)
D. H*(M-k-α)
Answer:A
Which of the following is equal to the value of H(k+α)?
A. H*(M-k+α) B. H*(M+k+α) C. H*(M+k-α) D. H*(M-k-α)
Explanation: Since {h(n)} is real, we can easily show that the frequency samples {H(k+α)} satisfy the symmetry condition
