A little bit off-topic but: Can anybody here direct me to a good book or
tutorial that would be able to recreate the "butter" function from scratch?
I've implemented an IIR filter to use the result of these Butterworth
values, but I'd ideally like to have the calculation directly in the
program (it is C++) -- also just for the purpose of knowing myself I
want to learn it.
P.S. I've already gone through several DSP references and have a good
idea on how to analyze filters, how to use the H(s) /z-transform, but
I'm just getting confused trying to pull it all together into producing
usable IIR filters... :(
