AsT becomes arbitrarily large, the original periodic square wave approaches a … WebAnswer (1 of 3): First, the DTFT is applied to discrete signals only. There is not a DTFT of a continuous signal. Then, if you sample the continuous signal f(t) to get a discrete f[n]=f(nT), and you get the DTFT of f[n] which is a discrete signal — so it now has a defined DTFT, — you still have ...

WebFeb 23, 2013 · 1. If you take the absolute value of the fft, you destroy the phase information needed to reconstruct the original signal, i.e. the moment you compute. X = abs (fft (x,N)); You cannot go back via ifft, because now you only have the magnitude. Also, the inverse transformation only works if you use the same number of FFT bins with NFFT>=length (x). how many rounds for bkfcWebJun 28, 2024 · In Digital Signal Processing (DSP) class, we implemet it use matrix.
