| Abstract: | With application of time-response and frequency response of discrete-time system with MATLAB, simulation and analysis on the system mathematical model are set up with futher study on the causality, stability, amplitude-frequency and phase-frequency characteristics of Discrete-time system.The result of simulation shows visual aid of Discrete-time system system characteristics, which provides the prerequisite foundation for reseaching on physical implementation and evaluating the quality of the digital communication system. |
