<p class="MsoNormal">3. Discussion on CIC compensation filters. MATLAB can generate a filter to compensate for passband droop and export the coefficients. This apparently also works (without graphics) in OCTAVE. Scotty mentioned there is a $50 student version
of MATLAB. Tom discussed measurements of gnuradio built-in time-domain windowing filter impact on FFT scalloping and other amplitude errors.<o:p></o:p></p>
