Does anyone know how the amplitude of a specific component
(or frequency) in the fourier domain is related to the
amplitude of that component in the time domain, and also the
number of points in the FFT?

It seems that the greater the NFFT, the smaller the
amplitude, but does anyone know the exact relationship?
