 March 2, 2006, 13:05 Re: WHAT IS "FFT" #2 Chris Bailey Guest   Posts: n/a You probably mean "Fast Fourier Transform", which is a calculation trick using successive divisions by two to calculate the Fourier Transform rapidly. Fourier transforms are ways to transform a dataset of a response variable of an independant variable into a sum (no doubt here a finite sum) of sine and cosine waves with integer frequencies through the dataset, having amplitudes calculated by the transform method. Often the independant variable is time or perhaps length.
