The frequency response of a filter is H(e j ) = 1.5 + cos(2),

Question:

The frequency response of a filter is H(e^jω) = 1.5 + cos(2ω),− π ≤ ω ≤ π.

(a) Is |H(e^jω)| = H(e^jω)? Is phase zero?

(b) Find the impulse response h[n]of this filter. What type of filter is it? FIR? IIR? Is it causal? Explain.

(c) Let H₁(e^jω) = e^−jNω H(e^jω) determine the value of the positive integer N so that H₁ (e^jω) has linear phase. Use the impulse response h[n] found above to find the impulse response h₁[n].
