Design a causal FIR based on the ideal filter normalized spectrum shown below: (pattern repeats every 2x) -2n 0 JI -3.2x -2.8 -1.2x -0.8x 0.& 1.2n 2.81 3.2n a.) Is this ideal filter shape low pass, high pass or bandpass. Briefly justify your answer. b.) Specify a formula for HIDEAL(@) using rect() function(s). c.) Specify a formula for the impulse response of the ideal filter, hIDEAL[n]. Briefly justify your answer and give values for n = -8, n = 0, and n = 8. d.) Specify a formula for the causal FIR filter, h27[n], that has a duration of 27 samples. Give values for n = -8, n = 0, and n = 8.
