The transform method of Bennett and Rice is used to obtain the output spectrum of a nonlinearly processed interferogram. The interferogram of a multi-element spectrum is considered as band-limited Gaussian noise. The theory is applied to nonlinear processing in holographic Fourier spectroscopy and inverse Fourier spectroscopy and to digital processing in conventional Fourier spectroscopy.
