1. Consider a signal x[n] = Determine the poles and ROC for X(z) ={S" cos(1). n < 0 n> 0 2. Use z transform to solve the following difference equation Yn+1 - 3yn = 4" Yo = 0 3. Obtain the Fourier transform of the signal in terms of X(el) if x[n] = x[1 – n] + x[-n - 1]. You may use the Fourier transform properties in table 5.1. below.
