Question: The following first-order IIR transfer function has been proposed for clutter removal in MT1 radars (Urk58):
H(z) = 1 - z-1
1 - kz-1
Determine the magnitude response of the above transfer function and show that it has a highpass response. Scale the transfer function so that it has a 0-dB gain at w = n. Sketch the magnitude responses for k = 0.95. 0.9. and -0.5. respectively.
