For each LTI system linear phase or nonlinear phase. identify whether the system has generalized Use the filter command to apply each of these 

For each LTI system linear phase or nonlinear phase. identify whether the system has generalized Use the filter command to apply each of these systems to the input sequence x[n] =u[n]+2u[n-20] -2u[n- 40] - u[n - 60], and plot the outputs you obtain using the stem command. Noting that the input sequence was symmetric, do you observe any qualitative differences in the outputs between linear and nonlinear phase filters that might make you prefer one over the other? y[n] = x[n - 1] y[n] + y[n - 1] = x[n] x[n - 1] y[n] = =x[n] + 2x[n - 1] - x[n - 2] y[n] = = 1 6 5 [n - k] . k=0 25 5 y[n] un] =(- (-)"an - 1 k] 6 k=0 25 he y[n] =(%) a[n k] k=0 (1) (2) (3) (4) (5) (6)
