Abstract
The carrier of information is the signal. The useful signals that we are interested are often in other similar or unsimilar mixed signal, which requires us to process the signal recorded in media, through the extraction, transformation, analysis, synthesis, and other means to obtain the useful information. So the science of signal analysis have emerged and even flourished. MATLAB has graphics capabilities and powerful symbolic manipulation functionality for us to achieve a visual signal in time domain and frequency domain analysis. In this paper, the continuous-time signal sampling is obtained and simulated by using Fourier transform. To this end, the parameters are given through keyboard, the corresponding results are computed by MATLAB interface.
