Chapter 3, Problem 3.14(choose chapter or problem)
QUESTION:
When the impulse train x[n] = L o[n - 4k] k=-X is the input to a particular LTI system with frequency response H(eiw), the output of the system is found to be (57T 7T) y[n] = cos 2 n + 4 . Determine the values of H(eikrr/2 ) fork = 0, 1, 2, and 3.
