Use Duality property of Fourier Transform to find the CTFT of the sinc … WebI'm not too sure it's even doable given the CTFT rect() function is not the aliased sinc() but the normalized sinc(). Deriving it from the finite geometric series is easy, but starting …
WebMay 22, 2024 · Basically what this property says is that since a rectangular function in time is a sinc function in frequency, then a sinc function in time will be a rectangular function in frequency. This is a direct result of the similarity between the forward DTFT and the inverse DTFT. The only difference is the scaling by \(2 \pi\) and a frequency reversal.
WebProblem 7 (Filtering). One thing that differs between textbooks is how they define the sinc function.
