For this question, the original signal is a square wave with maximum amplitude one, minimum amplitude zero and period P. The ideal low pas filter is a band that goes from -fc to fc with constant amplitude one. Once filtered (for part a), the signal is once period of the original signal that starts at -1e-4 and goes to 1e-4. The ideal sampler creates a discrete signal with 5 points each 5e-5 apart.

From here, I am not sure what to do. I feel as if the amplitude should be adjusted by 1/period, but I am not sure. Currently, we are in the time domain, but the digital filter is in the frequency domain. How do you apply this filter? Any ideas are helpful. Thanks! --Babaumga 12:27, 11 February 2009 (UTC)
