 Fourier Analysis Mathematica provides broad coverage of both numeric and symbolic Fourier analysis, supporting all standard forms of Fourier transforms on data, functions and sequences, in any number of dimensions, and with uniform coverage of multiple conventions. Fourier Transforms FourierTransform, InverseFourierTransform — complex Fourier transforms (FT, IFT) Fourier Series FourierSeries — truncated complex Fourier series to any order FourierCoefficient — nth coefficient in a Fourier series Fourier Sequence Transforms FourierSequenceTransform — discrete-time Fourier transform (DTFT) InverseFourierSequenceTransform — inverse transform (IDTFT)      Discrete Fourier Transforms Fourier, InverseFourier — discrete transforms of lists of data in any dimension (DFT) FourierDST, FourierDCT — discrete sine, cosine transforms (DST, DCT, types I-IV)      FourierParameters — select between Fourier analysis conventions      Convolutions      Related Transforms Related Functions MORE ABOUT Integral Transforms Signal Processing Image Processing Calculus Discrete Calculus RELATED LINKS How to: Do Calculus
