"WebThe fast Fourier transform (FFT) is a discrete Fourier transform algorithm which reduces the number of computations needed for N points from 2N^2 to 2NlgN, where lg is the base-2 logarithm. FFTs were first discussed by Cooley and Tukey (1965), although Gauss had actually described the critical factorization step as early as 1805 (Bergland 1969, Strang … " - Software fft

WebSep 28, 2024 · The output of a mathematical FFT will always be in the same units as the input. So if the input array to a software FFT is a series of voltage measurements, the output FFT array will be in units of Volts. For some FFT software functions, there is an additional step that converts the FFT output to dB and passes that back to the caller. WebOverview. NFFT is a software library, written in C, for computing non-equispaced fast Fourier transforms and related variations. It implements the following transforms: Non-equispaced fast Fourier transform (NFFT) forward transform (NFFT), i.e. frequency to time/space domain. adjoint transform (adjoint NFFT), i.e. time/space to frequency domain.
