the term 'polyphase components' stands for the Type 1 com- ponents with M = 2. a) Let H(z) represent an FIR filter of length 10 with impulse response coeffi- cients h(n) = (1/2)" for 0 n 9 and zero otherwise. Find the polyphase components Eo(z) and E (z). b) Let H(z) be IIR with h(n) = (1/2)^U(n) + (1/3)^U(n-3). Find the polyphase components Eo(z) and E1 (z). Give simplified, closed form ex- pressions.
