For the case where r[n] = {1,3,5, -2,3} and h[n] = {1,2,5, -2, 1,6,3)}, (a) Compute y[n] = a[n] *h[n], perhaps using conv. (b) How long is the output sequence? Give the relation of the length of y[n] as a function of the lengths of x and h. (c) Draw stem plots of both inputs and the output. (d) Construct a simple SIMULINK block diagram to verify the solution by using a single FIR filter and a short input sequence. man Repeat sequence U Ts=1 us 1+2245222241246z-432-6 1 Discrete FIR filter under test Y
