(b) A real-valued signal, which is absolutely summable, which has the following irrational z- transform X(2) = X1(z) - X1(2-), where X1(x) = (1 +0.52-2-3/2 (1) Expand X1(x) and hence express X(z) using a power series expansion method. please turn the page over 1 (ii) From the above step, find 1(n), the inverse z-transform of X (2) its ROC. (i) Plot 1(n), showing only 8 significant number of terms. (iv) Find the energy of r(n). (v) Determine and plot the magnitude of Fourier transform.
