Okay, I think I understand the zero padding a bit better now, thanks for the link, very nice graphics. So here we have a sine wave fit into FFT on the page 31, and then it starts to get zero padded and indeed the FFT does start to include other frequencies than the fundamental (and of course the...
Thanks for the article, it was good read.
What I still don't understand is when you add zeroes, it appears that the FFT only gains resolution. I would just intuitively think that say a single cycle of sine wave padded by 1 zero is going to be a radically different signal from a sine wave padded...
Thanks a lot for yourr esponse weetabixharry!
I will try to clarify my question a bit at the end of this response, maybe the question was not fully understod by everyone.
"Exactly" is the important word here.
Exactly, the 1,000,000.1 cycle sine is not a perfect sine wave, and as such does...
Hey,
I am new here, and currently trying to work my way through the "The Scientist and Engineer's Guide to Digital Signal Processing" by Smith. There is one question that keeps bugging me about this whole FFT thing, and I think it's elementary in understanding it. I don't ever intend to be a...
