For part b, please explain how to implement a bandpass filter
with the given specifications?
(a) Determine the unit impulse response h1 [n] of an ideal discrete-time lowpass filter with cutoff frequency we = a/5. (b) Determine the unit impulse response he[n] of an ideal discrete-time bandpass filter satisfying the following specification: BOTSWT otherwise. Ha(w) = { ; Hint: Use the result from (a) and the DTFT pair, cos(won)[n] 3Xd(w-wo) + Xd(w +wo). ) (c) Determine a length-7 causal GLP FIR filter [] that approximates the above desired bandpass filter h2[n] using a rectangular window design.
