4. (30 pts) Let x[n] be a sequence of complex numbers defined as x[n] = 7ej(0.22.11n-0.25T) for integers n such that -~<n<oo. If we define a new sequence y[n] as follows = y[n] = x[n + 1] - 2x[n] + x[n - 1], for all n. It is possible to express y[n] in the form y[n] = Aejdejw." + - (a) Determine the frequency wo in the expression for y[n] (b) Determine the numerical values of A and
