WebThis 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 ω ∗ t d t. However carrying out the relatively simple integration and subbing in the bounds results for me in this: X ( ω) = 1 j ω [ e − j ω − 1] http://alwayslearn.com/DFT%20and%20FFT%20Tutorial/DFTandFFT_TheDFT.html frozen peas aldi
