Please answer ni MATLAB question when able. Thanks.

In this exercise, we will synthesize the output of an artificial echo generator with two reflection terms. White an M-file script that generates the input signal x(n), shown in Fig 4.8 below, and then computes the output signal y(n) of the discrete-time system specified by the following equation: (n)x(n)+x(n-15)-+r(n-30) 4 Make a subplot of the signals x(n) and y(n) for comparison. Save your script as 'exer_4_2.m. Make a list of commands you employed in your script in the space provided belovw. Input Signal, x(n) 10 -5 -1 20 60 80 100 120 Fig. 4.8.
