: The frequency response of an ideal low-pass filter is: ||H(ejw)| = {1 − ˜/4 ≤ w≤π/4 . otherwise and_ZH(ejw) = -π/2, w≥0 π/2, ω < 0 a) Calculate the impulse response h(n) of the filter. b) If the above filter is connected in series with a defective sinusoidal signal generator that gives sinusoids of x(n) = 1.5 cos (2nπ/3), for what frequency (or frequencies) is the filter output y(n)?
