The transfer function of an FIR filter is H(z) = z 2 (0.5z + 1.2 + 0.5z

Question:

The transfer function of an FIR filter is H(z) = z ⁻²(0.5z + 1.2 + 0.5z⁻¹).

(a) Find the frequency response H(e^jω) of this filter. Is the phase response of this filter linear?

(b) Find the impulse response h[n] of this filter. Is h[n] symmetric with respect to some n? How does this relate to the phase?
