WebMay 22, 2024 · Introduction. This module will look at some of the basic properties of the Continuous-Time Fourier Transform (CTFT) (Section 8.2). Note. We will be discussing … 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 from the CTFT seems harder. $\endgroup$ – Yannick. Aug 26, 2024 at 4:14
