i. The coefticients of an N th order (length N+I ), where N is even) FIR filter H(z) is denoted as h[n]. N/2nN/2. Express the condition that should be satisfied by the coefficients h[n] of the FIR filter in order to have a zero-phase response. [05marks] ii. The ideal frequency response of a zero-phase bandpass filter H(z) is specified as H1(ef)={1,0,for1uotherwise, where , and and (0
