Hello,
your code is just fine.
Try plotting the two signals in a larger time window, for example
[-1 1] and not [-0.1 0.6] and you will see that the initial signal has undergone
just a delay.

Hello everyone,
I was wondering if anyone could give me their insight to this problem.
I am trying to understand how to use a bandpass filter in butter to pass only a
certain band of frequency.
This works for a simple cosine with one frequency, but with a summation of
cosines..
The output signal should be the same, right? Or is this due to some sort of
transient response? It looks like just a change in delay. Any insight would be
much appreciated. Thanks!
