The DFT has many applications, including purely mathematical ones with no physical interpretation. But physically it can be related to signal processing as a discrete version (i.e. samples) of the discrete-time Fourier transform (DTFT), which is a continuous and periodic function. The DFT computes N equally … 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 $${\displaystyle N}$$-periodic. Accordingly, other sequences of $${\displaystyle N}$$ indices are sometimes used, … 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 discrete variable n. The multidimensional … 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 The discrete Fourier transform is an invertible, linear transformation $${\displaystyle {\mathcal {F}}\colon \mathbb {C} ^{N}\to \mathbb {C} ^{N}}$$ with 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 WebNov 22, 2024 · High defibrillation threshold with right-sided ICD implantation was resolved by a dual coil lead via persistent left superior vena cava J Cardiol Cases. 2024 Nov 22;25 (5):262-265. doi: 10.1016/j.jccase.2024.10.012. eCollection 2024 May.
