Definition of fft in English English dictionary
- fast Fourier transform
- Fast Fourier Transform A specific efficient spectral analysis program
- Fast Fourier Transform; an algorithm for converting data from the time to frequency domain; often used in signal processing
- Fast Fourier transform A quick method of performing a Fourier analysis on a sound See Fourier analysis
- An acronym for Fast Fourier Transform, a technique for very fast computation of Fourier series A discrete Fourier transform using N points can be computed in N log N steps by the fast method, whereas the straightforward method would take N**2 steps
- > Fast Fourier transform
- (Fast-Fourier Transform) A method by which a system is described using an impulse response Both frequency and time data can be extracted, with room reflections removed, providing an extremely accurate analysis Mathematical manipulation of the data is employed to view system parameters from a variety of perspectives 1
- (n ) The fast Fourier transform is a technique for the rapid calculation of discrete Fourier transform of a function specified discretely at regular intervals The technique makes use of a butterfly data structure
- (Fast Fourier Transform): A mathematical function describing the relative magnitudes and phases of frequencies in a time varying signal
- Fast Fourier Transform: a computationally efficient algorithm for implementing the Discrete Fourier Transform which is used to transform discrete data from the domain of time or space to the frequency domain
- a fast algorithm for the computation of the discrete Fourier transform (DFT) y0, , yn - 1 of a sequence of n complex numbers x0, , xn - 1, yk = xje2ijk/n , typically requiring only O(n log n) arithmetic operations -- or a multi-dimensional generalization thereof By contrast, straightforward, or naïve evaluation of the DFT requires O(n2) operations
- The computer implementation of Fourier Transforms produces a finite series of sine and cosine waves
- Spectral Analysis
- Fast Fourier Transform A computationally efficient mathematical technique which converts digital information from the time domain to the frequency domain for rapid spectral analysis
- Full Name: Fast Fourier Transform Description: Converts analog waveforms into a form that can be easily analyzed for DSP applications
- Fast Fourier Transform -- a procedure for calculating discrete frequency components from sampled time data Special digital signal processing chips perform FFTs in today's oscilloscopes
