WebThe Fourier transform of a "comb function" is a comb function? Let f(x) = ∑∞n = − ∞δ(x − n), where δ is the Dirac delta function. This function f (a "comb function") is important … http://abut.sdsu.edu/TE302/Chap4.pdf

Discrete-time Fourier Transform of the unit step sequence

WebWe can get the DTFT as: H ( e j ω) = − 1 So the magnitude will be 1, and according to my understanding, the phase is calculated as tan − 1 ( ℑ { H } ℜ { H }) = tan − 1 ( − 0 1) = 0 But in the document, the phase is π.
