Exempel på hur man kan använda FFT i en mening

• A fast Fourier transform (FFT) is an algorithm that computes the Discrete Fourier Transform (DFT) of a sequence, or its inverse (IDFT).
• In November 2010, NEC announced that ES2 topped the Global FFT, one of the measures of the HPC Challenge Awards, with the performance number of 11.
• Another important application of trigonometric tables and generation schemes is for fast Fourier transform (FFT) algorithms, where the same trigonometric function values (called twiddle factors) must be evaluated many times in a given transform, especially in the common case where many transforms of the same size are computed.
• This method utilizes fast Fourier transform (FFT) that converts amino acid sequences into a sequence composed of volume and polarity values for each amino acid residue.
• Rader of MIT Lincoln Laboratory, is a fast Fourier transform (FFT) algorithm that computes the discrete Fourier transform (DFT) of prime sizes by re-expressing the DFT as a cyclic convolution (the other algorithm for FFTs of prime sizes, Bluestein's algorithm, also works by rewriting the DFT as a convolution).
• SciPy contains modules for optimization, linear algebra, integration, interpolation, special functions, FFT, signal and image processing, ODE solvers and other tasks common in science and engineering.
• Though the museum did not receive one of the four remaining Shuttles, it did receive the Full Fuselage Trainer (FFT), a Shuttle mockup that was used to train all Space Shuttle astronauts.
• James Cooley and John Tukey publish the general version of the Fast Fourier transform which becomes known as the Cooley–Tukey FFT algorithm and significant in digital signal processing.
• A Fistful of TOWs, often abbreviated FFT, is a series of modern warfare miniatures wargame rules first published in 2000.
• Other analysis tools include FFT, integration and differentiation, splines, interpolation, and smoothing.
• Modern enthusiasts often monitor the transmissions using a PC with a coil connected to the soundcard input and FFT analysis software, or a short-wave receiver with an upconverter, or any of several receivers designed to receive VLF transmissions directly.
• By using FFT (fast Fourier transform), used in the original version rather than NTT (Number-theoretic transform), with convolution rule; we get.
• These junctions were classified firstly by the types of plate boundaries meeting – for example RRR, TTR, RRT, FFT etc.
• Danielson on what is now called the fast Fourier transform (FFT, 1940), but the significance of his discovery was not appreciated at the time, and today the FFT is credited to Cooley and Tukey (1965).
• Moreover, experimental data can be analyzed with additional tools such as an oscilloscope, FFT spectrum analyzers, boxcar averager or used to provide feedback by using internal PID controllers.
• The complex OFDM electronics, including the FFT algorithm and forward error correction, are constantly active, thus consuming power, independent of the data rate, while OFDM combined with data packet scheduling may allow FFT algorithm to hibernate at times.
• Compared to DFT (or FFT), which is characterized by perfect spectral resolution, but poor temporal information, SCA favours temporal information, but yields higher spectrum dispersion.
• Most commonly, the term "butterfly" appears in the context of the Cooley–Tukey FFT algorithm, which recursively breaks down a DFT of composite size n = rm into r smaller transforms of size m where r is the "radix" of the transform.
• The prime-factor FFT algorithm is one unusual case in which an FFT can be performed without twiddle factors, albeit only for restricted factorizations of the transform size.
• 20 MHz channel uses an FFT of 64, of which: 56 OFDM subcarriers, 52 are for data and 4 are pilot tones with a carrier separation of 0.
