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
dt=.001; %sampling rate
Fs=1/dt; %sampling freq
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!
Simple butter filtering question!
