WebMay 29, 2024 · The DFT is defined on a finite interval. So, if you are asking for the DFT of your function, the answer will depend on your interval definition. Your function is not periodic. The DFT of the continuous sinc is not going to be a "clean" answer. In the continuous realm, sinc and rectangular functions are Fourier pairs. – Cedron Dawg WebSep 19, 2024 · The rectangular function is an idealized low-pass filter, and the sinc function is the non-causal impulse response of such a filter. 12 s i n c 2 ( a t ) {\displaystyle …
Web1 I'm trying to find the Fourier Transform of the following rectangular pulse: x ( t) = r e c t ( t − 1 / 2) This is simply a rectangular pulse stretching from 0 to 1 with an amplitude of 1. It is 0 elsewhere. I tried using the definition of the Fourier Tranform: X ( ω) = ∫ 0 1 ( 1) ∗ e − j … WebApr 24, 2024 · Recall the Fourier transform's theorem: F { x [ n] e j ω 0 n } = X ( ω − ω 0) where F { } is, in this case, the Discrete-Time Fourier Transform (DTFT). which is a box …
