4. (20 pts) Consider an LTI system with the impulse response: h[n] = 26[n] + 2¯"u[n]. (a) (5 pts) Find H(e), the Fourier Transform of h[n]. (b) (5 pts) Find the difference equation describing this system. (c) (10 pts) For x[n] = (−1)” as the input, find Y(e¹w) = F{y[n]}, i.e., the Fourier Transform of the output. Hint: (−1)ª can be represented with a complex exponential.
