What is the Fourier Transform of a constant signal?
WebI am trying to figure out what the fourier transform of a constant signal is and for some reason i am coming to the conclusion that the answer is 1. Or better yet a step function. the continuous Fourier Transform of a constant is not 1 (a constant), but is a dirac delta function. and that is not 1.
