Question
Let x[n] = (n+1)3n u[n+2]. a- Give the z-transform Y(z) of y[n] = x[n-2]. You do not need to simplify it. Warning: Warning 1. b- [ ] Deduce from the previous question the z-transform X(z) of x[n]. Put it into a fraction of two polynomials. Warning: Beware of sign mistakes in the powers of z. C- ] Plot the sequence v[n] such that x[n] = (n+1)3" u[n] +v[n]. d-. Deduce from the previous question another way to derive X(z). Show that you are getting the same result as in question b. Remark: The matching with b is a good way to check that there are no mistakes in your derivations in this problem.
