WebSep 11, 2024 · The FFT algorithm, which computes the Discrete Fourier Transform (DFT), is only applicable to discrete-time signals of finite duration, i.e., signals x[n] that are zero for n larger/smaller than an upper/lower bound.So no, fft can't be applied to sin(t) or exp(-a*t^2) (note that sin(t) is a different animal because it doesn't have convergent Continuous … WebRecall that the integral of sine or cosine over an integer number of cycles is zero (it spends half the cycle above zero and half below, each at the same height, so the net area over a single cycle is exactly zero). So, in general, Euler’s formula plus this idea tells us, for any nonzero integer k, that: Z <2ˇ> ej!k= Z <2ˇ> cos(!k)d!+j Z ...
