(30 pts) Consider the following discrete-time LTI system: x[n] hi[n] where x[n] = sin(n+) and h₁ [n] = h₂[n] = (²)"u[n]. (a) (10 pts) Find the overall frequency response of this system. (b) (10 pts) Find the Fourier Transform of the input, x[n]. (c) (10 pts) Find the Fourier Transform of the output, y[n]. h₂ [n] y[n]
