- A real-valued signal, which is absolutely summable, which has the following irrational - transform X(z) = X1(z) - X1(2-1), where 1 X1(2) = (1 - 2-2/2)3/2 (i) Expand X1(z) and hence express X(z) using a power series expansion method. (ii) From the above step, find x(n), the inverse z-transform of X(2) its ROC. (iii) Plot x(n), showing only 8 significant number of terms. (iv) Find the energy of x(n). (v) Determine and plot the magnitude of Fourier transform.
