More Book Details

Description of the Book:

The correlation function of two signals can rapidly be obtained by taking the inverse discrete fast Fourier transform (IDFFT) of the product of the discrete fast Fourier transform (DFFT) of the first signal times the complex conjugate of the DFFT of the second signal. The subroutine RAPIDC accomplishes this operation
