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

Question:

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

(a) Find the impulse response h[n] of this filter and plot it. Comment on any symmetries it might have.

(b) Find the phase ∠H(e^jω) of the filter and carefully plot it. Is this phase linear for all frequencies − π < ω ≤ π?
