Hi, I have a question about the FFT. I'm starting to learn the concepts behind it, but I'm struggling at this one particular thing... Ok, lets say you have this diagram. http://www.ece.uvic.ca/499/2004a/group05/image/radix2.jpg Can someone explain to me exactly what "N-point" means? Also, what a "point" is? And... what exactly does into these inputs... like x(0) and x(1) and ... x(15)? Are they complex numbers? 1s and 0s? Maybe 1 sample size per x(#) of 16 bits? As you can see, I'm pretty much confused on how this actually works and how to interact with it. Thanks!
