The overall system in the dotted box in Figure can be shown to be linear and time

Question:

The overall system in the dotted box in Figure can be shown to be linear and time invariant.

(a) Determine an expression for H(e^j?), the frequency response of the overall system from the input x[n] to the output y[n], in terms of H₁(e ^j?), the frequency?response of the internal LTI system. Remember that (? 1)ⁿ = e^j?n.

(b) Plot H(e^j?) for the case when the frequency response of the internal LTI system is?
