Thank you wukunlin.
It's really hard for me to picture that. I can picture a sin wave that is shifted up/down the y-axis and I assume that this is the effect of a DC offset. Now when I apply the filter, how would the filter know that these are actually two signals, one 0 frequency signal and...
Hello all,
I want to filter DC offset for a signal by applying a high-pass filter to it (I've been told that to filter the DC offset this is what I should do - I'm not sure why exactly!)
My question is; do I do that in the time-domain or frequency-domain after applying FFT? And I would...
