Question 1 [20%]:
Determine all possible signals x[n] associated with the z-transform X(z) = (1 5z 1 2z 1 )(3 z 1) .
Question 2 [25%]:
Determine the coe cients {h[n]} of a high-pass linear-phase FIR lter of length L = M + 1 = 4 which has an antisymmetric impulse response, i.e. h[n] = h[M n], and a frequency response H(e|! ) that satises the condition |H(ej/4 )| = 0.5 and |H(ej3/4 )| = 1.
