Can someone please help me with these questions asap? Thank you very much!!

Unit impulse response 1) In this assignment, we will find the unit impulse response h[n] for the following systems. Use filter command from MATLAB to determine h[n] and then sketch the result. to determine hlpl and then sketch ther the following 2 N 2) To verify your answers, calculate h[n] by hand. You need to find characteristic modes and then compute the impulse response (See example 3.18 in the textbook) 3) Check if the value of h[3] is the same in both methods. Note: All the initial conditions are zero
