Problem Statement
Use Octave (or Mathlab or Silab) to plot the frequency response of low pass filters with cut off frequencies of 1/32T, 1/8T, and 1/4T and compare how many coeffficients are needed with an eye to answer the question “Is it less calculation to decimate and then filter, or better to put the filter in the pre-decimation filter?”
