Let x[n] = -(1)/(a^(n))u[-n-1] and x[n] approaching Z-transform x[Z]. Assume a = last digit of your ID number + 1 (e.g. if the last digit of your ID number is 8, then a is 9).
a) Write a MATLAB code to find x[Z].
b) Plot x[n].
c) Plot ROC and write its value.
c) Plot ROC and write its value. b) Plot x[n]. a) Write a MATLAB code to find X[Z]. For example, if the last digit of your ID number is 8, then a is 9. Let x[n] = -u[-n-1] and x[n] Z-transform.
