Consider an FIR filter with impulse response h[n] = 8[n] 8[n 1] + 8[n 2]. (a) (3 pts) Compute the transfer function H(2) and frequency response H(ej). (b) (10 pts) Compute and sketch the magnitude response and phase response of H(e). For the phase response, sketch it within the principal value [-, ). (c) (2 pts) Is this a linear-phase FIR filter? If yes, which Type (Type 1 to 4)? If no, explain why.
