Here is my attempt to 2a) and some of 2b).
Question:

In b)i) it asks for the spectra at each node of the block diagram. Now, using the discrete low pass filter described in a),
would still give the same Yd (ejΩ) as in a) since the aliased parts are filtered out from -pi/2 to pi. If this is the case, why
does it mention new specifications for Hd (ejΩ) to obtain same Yd (ejΩ) as in a) ? I appreciate any guidance thanks.
