The discrete Fourier transform is an invertible, linear transformation $${\displaystyle {\mathcal {F}}\colon \mathbb {C} ^{N}\to \mathbb {C} ^{N}}$$ with $${\displaystyle \mathbb {C} }$$ denoting the set of complex numbers. Its inverse is known as Inverse Discrete Fourier Transform (IDFT). In other words, for any … See more In mathematics, the discrete Fourier transform (DFT) converts a finite sequence of equally-spaced samples of a function into a same-length sequence of equally-spaced samples of the discrete-time Fourier transform (DTFT), … See more Eq.1 can also be evaluated outside the domain $${\displaystyle k\in [0,N-1]}$$, and that extended sequence is $${\displaystyle N}$$ See more It is possible to shift the transform sampling in time and/or frequency domain by some real shifts a and b, respectively. This is sometimes known as a generalized DFT (or GDFT), … See more The DFT has seen wide usage across a large number of fields; we only sketch a few examples below (see also the references at the end). All applications of the DFT depend … See more The discrete Fourier transform transforms a sequence of N complex numbers $${\displaystyle \left\{\mathbf {x} _{n}\right\}:=x_{0},x_{1},\ldots ,x_{N-1}}$$ into another sequence of complex numbers, The transform is … See more Linearity The DFT is a linear transform, i.e. if $${\displaystyle {\mathcal {F}}(\{x_{n}\})_{k}=X_{k}}$$ and See more The ordinary DFT transforms a one-dimensional sequence or array $${\displaystyle x_{n}}$$ that is a function of exactly one … See more WebApr 13, 2024 · DFT studies were performed with Gaussian 16 software (Frisch et al., 2016). ...
