Abstract :
A technique has been developed to locate the peak of a spectral component within a resolution cell of a Fast Fourier Transform Spectrum. An iterative approximate curve fitting process is applied to the spectral magnitude at two adjacent frequency points in the immediate vicinity of the expected component peak. A correction factor is computed from which the exact location of the component peak can be determined.
