Please solve the question in matlab.

Unit impulse response of an LTI system is shown below h(n)=(0.6) [u(n) -u(n - 2001 a. Determine the system defined by h(n) whether stable or not. b. x(n)=3.cos(0.5nn) length of x(n) =256 x(n) is the input of the system defined by h(n), so compute the output y(n) using; convolution (in time) multiplication (in frequency) Draw the two output signals y(n) computed in two different manners, in one figure (top and bottom). c. Parseval theorem says that total energy contained in a waveform x(n) summed across all of time n is equal to the total energy of the waveform's Discrete Fourier Transform X(K) summed across all of its frequency components k. The equation is given below. Show the Parseval Theorem's validity for the signals calculated at (b) N-1 1 [ n |x[n]|2 -N-1 |x[k]] k=0 n=0 N Unit impulse response of an LTI system is shown below h(n)=(0.6) [u(n) -u(n - 2001 a.
