Quote:Difference between Fourier Series and Fourier Transform
Fourier series is an expansion of periodic signal as a linear combination of sines and cosines while Fourier transform is the process or function used to convert signals from time domain in to frequency domain. Fourier series is defined for periodic signals and the Fourier transform can be applied to aperiodic (occurring without periodicity) signals. As mentioned above, the study of Fourier series actually provides motivation for the Fourier transform.
I used fft in my work many years ago (almost 30) while working R & D in spectra-chemical instrumentation design and honestly can't remember enough to properly answer your question.
