[SciPy-user] Lowpass Filter

Hi list!

Let's suppose a to be a 1D array with N elements.
Basically, it's a signal of some sort.

How do I apply a low pass filter (with selected frequency and width)
to this signal?
How to store the resulting, filtered, signal, in a new array?

I had a look at lp2lp() in scipy.signal, but it returns, if I am
right, a filter object, which then I dunno how to use to filter my
data.

Any ideas or pointers?

TIA,

marco
