Hi,
Thanks for your reply!
Renaming doesn't work, but what I found out is, that, in my case, it
works with the following syntax:
sum(function for n_ in np.arange(-11,11,1))
Nevertheless, I'd be interested if there are other people out there
working with Signal Theory and stochastic signal descrip

Hi,
I got a first result, but it only works when I "type" it in the command
line interface.
import numpy as np
import pylab as pl
pl.ion()
pl.grid(True)
var('t n_ ll ul')
tt=np.arange(0.01,10,0.01)
f=sin(t)/t
ts=0.5
fs=sum(f*dirac_delta(t-(2*n_-1)*ts),n_,0,20)/dirac_delta(0)
fl=lambda t:f

Hi,
I played with the dirac_delta function but didn't get the results that I
need.
In the end, I need to be able to plot and calculate functions that are
multiplied with a dirac comb like

But I didn't find out how to do
