[SciPy-user] signal.butter questions

I have two questions about signal.butter.  First, I don't see it in
the docstring, but I am assuming the Wn must be normalized by dividing
by the Nyquist frequency.  Is that true?  It seems like that is what
buttord is saying and I assume they use the same conventions.

Second, what is meant by the analog keyword?

Thanks,

Ryan
