Ctft using matlab
WebAn exact Continuous-Time Fourier Transform (CTFT) cannot be performed accurately by the computer. Instead, MATLAB does a digital approximation. The approximation uses the Discrete Fourier Transform (DFT). There are two main differences between the CTFT introduced in class and the DFT used in MATLAB.
