QUESTION
Let h[n] = (0.6)^n*sin(3n/5)*u[n]. Find the system output when x[n] = 1 + cos(3n/5) + (1)^n. I get the DTFT of h[n] already. what's the DTFT of x[n]
Let h[n] = (0.6)^n*sin(3πn/5)*u[n]. Find the system output when x[n] = 1 + cos(3πn/5) + (−1)^n.
I get the DTFT of h[n] already. what's the DTFT of x[n] and how to get y[n] after IDTFT? Some steps pls.
