===Question 14=== I am adjusting for frequency warping and then performing a bilinear transform to realise my digital filters. I am using the function "freqz" to plot the frequency responses of the digital filters. When plotting the frequency responses, and looking at the 3dB frequency, it seems that I can be 5 Hz to 10 Hz off the desired frequency, depending on the filter. Is this an acceptable error? Or am i doing something horribly wrong? :'''Answer 14:''' The 3 dB freqs are in the order of kHz, so an error of 10 Hz is negligible! Don't worry. (If you had a 10 kHz error, now that would be a serious problem).
