The desired frequency response is specified at a set of equally spaced frequencies defined by the equation:
A. π/2M(k+α)
B. π/M(k+α)
C. 2π/M(k+α)
D. None of the mentioned
Answer:A
The desired frequency response is specified at a set of equally spaced frequencies defined by the equation:
A. π/2M(k+α) B. π/M(k+α) C. 2π/M(k+α) D. None of the mentioned
Explanation: To derive the frequency sampling structure, we specify the desired frequency response at a set of equally spaced frequencies, namely ωk=2π/M(k+α) ,k=0,1…(M-1)/2 for M odd
