What is the FFT of a sine wave?

The FFT. The function fft( ) estimates the coefficients of the Fourier transform, transforming a time-domain signal (i.e., an observed fMRI time series) into a series of sine waves with different amplitudes and phases. Fourier coefficients are complex numbers, with values in the real and imaginary planes.
