(5pts) k. 0 (b) what is the response of this lter to an input of the form: (15pts) x[n] = n u[n] where u[n] = (cid:26) 1 n 0. Make sure you specify y[n] for all n. For n 4: y[n] = 1. 5 x[n] + 2. 5 x[n 1] + 2. 0 x[n 2] + 1. 0 x[n 3] + 0. 5 x[n 4] = 1. 5(n) + 2. 5(n 1) + 2. 0(n 2) + 1. 0(n 3) + 0. 5(n 4)
