WebMay 22, 2024 · In this module, we will derive an expansion for any arbitrary continuous-time function, and in doing so, derive the Continuous Time Fourier Transform (CTFT). Since complex exponentials (Section 1.8) are eigenfunctions of linear time-invariant (LTI) systems (Section 14.5), calculating the output of an LTI system given as an input amounts to ... Web"FFT algorithms are so commonly employed to compute DFTs that the term 'FFT' is often used to mean 'DFT' in colloquial settings. Formally, there is a clear distinction: 'DFT' refers to a mathematical transformation or function, regardless of how it is computed, whereas 'FFT' refers to a specific family of algorithms for computing DFTs."
WebFeb 23, 2013 · 1. If you take the absolute value of the fft, you destroy the phase information needed to reconstruct the original signal, i.e. the moment you compute. X = abs (fft (x,N)); You cannot go back via ifft, because now you only have the magnitude. Also, the inverse transformation only works if you use the same number of FFT bins with NFFT>=length (x). WebDec 16, 2009 · Conceptually we are traveling methodically toward the discrete Fourier transform, or DFT, which is what the MATLAB function fft computes. Along the way we'll figure out how all three forms (continuous …
