2. (I 5 pts) Consider an FIR lter with tmnsfer funetien H[z) = %(l + 3"] + 32}. {a} (2 pts} 15 this a linearphase FIR lter? If so, which type {Type 1 to 4}? {h} (3 pts} Detelmine the Mueney response of the lter. (e) (8 pts} Determine the magnitude respense and phase response of the lter, and sketch them. For the phase reapenee, sketch it within the plineipal value [11", if}. (t1) (2 pts) Determine the group delay of this lter
