Question

A discrete-time system has the following unit-pulse response: $h[n] = ((0.5)^n - (0.25)^n)u[n]$ Find the response of this system to $x[n]$ when: 21- (a) $x[n] = u[n]$, 22- (b) $x[n] = sin(n\pi/4)u[n]$, 23- (c) $x[n] = u[n] + sin(n\pi/4)u[n]$, matlab code please don't write it on paper write the code on the computer please I need

I NEED MATLAB CODE. PLEASE DON'T WRITE IT ON PAPER, WRITE THE CODE ON THE COMPUTER PLEASE!!! A discrete-time system has the following unit-pulse response: h[n] = (0.5 - 0.25)u[n] Find the response of this system to x[n] when: (a) x[n] = u[n] (b) x[n] = sin(nÏ€/4)u[n] (c) x[n] = u[n] + sin(nÏ€/4)u[n] I need MATLAB code. Please don't write it on paper, write the code on the computer please.
