WebTime reversal of a sequence . The Time reversal property states that if. It means that the sequence is circularly folded its DFT is also circularly folded. 8. Circular Time shift . The Circular Time shift states that if. Thus shifting the sequence circularly by „l samples is equivalent to multiplying its DFT by e –j2 ∏ k l / N . 9. WebAny signal that is stored in a computer must be a nite length sequence, say x[0];x[1];:::;x[L 1]:Since there are only Lsignal time samples, it stands to reason that we should not need …

WebApr 25, 2024 · 1. Take a look at this answer to the same question. It's because the FFT is just a fast or optimized method to compute the DFT. And the DFT is precisely the same math as the DFS, the Discrete Fourier Series. And Fourier Series is about periodic functions. – robert bristow-johnson.
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), which is a complex-valued function of frequency. The interval at which the DTFT is sampled … 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, See more The discrete Fourier transform is an invertible, linear transformation 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), also called the shifted DFT or offset DFT, and has analogous properties to the … 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).
