Rik,

You want to filet the signal. There are a couple of filter signals in
the signal package. Assuming you have 3.6 or above version of Octave,
do

pkg install -forge specfun control optim general signal

(there may be other dependencies, pkg will tell you)

Once you installed it run

pkg load signal
lookfor filter

It will give you the list of functions with the word filter in their help text.


I hope that is useful
