[SciPy-user] Help with filter design

Forgive these questions if they are rather basic. I am trying to get up to
speed with python and the scientific packages. I have an implementation of a
dsp process for a software radio implemented using Intel IPP. I am
converting this to python. One of the things I need to do is fast
convolution filtering. To create the filter in IPP I do something like:
ippsFIRGenLowpass_64f( ( high_cutoff - low_cutoff )/2, taps, no_of_taps,
window_type ) ) where taps is the output array.

Is there something similar in SciPy or other packages. I found the tutorial
in the signal processing area too difficult to follow and I can't seem to
locate any other documentation for SciPy except the help where you really
need to know what you are looking for.

Any assistance appreciated
Bob
