信号与系统分析软件研究

RESEARCH ON SOFTWARE PLATFORM FOR SIGNALS AND SYSTEMS ANALYSIS

信号与系统分析中很多方法较为抽象,计算繁琐,借助Visual Basic(VB)和MATLAB程序设计语言的强大功能,设计并开发出了信号与系统分析软件平台。软件平台包括了连续信号与系统的时域分析方法和变换域分析方法,以及离散时间信号的时域和Z域分析方法等信号与系统中的主要内容。此外,还包括了滤波器设计等内容。对软件功能的设计、以及实现中的关键技术等进行了详述。软件的研制,使得信号与系统分析中复杂抽象的理论变得简单直观,软件界面友好,功能完善,实际应用取得了良好效果。

It is abstractive in many methods and eomplex in computation for signals and systems analysis. According to this characteristic, a set of software platform was designed and developed based on powerful functions of Visual Basic and MATLAB programming language. It in eludes the main contents of signals and systems analysis, such as time domain analysis and transform domain analysis for continuous signals and systems, time domain analysis and Z-domain analysis for discrete time signals, etc. Besides, methods for filter design are also discussed. The key technologies to software function design and implementation are presented in detail in this paper. This research makes the complex and abstract theory in signals and systems analysis easy and straightforward. This software has perfect functions as well as friendly interface. Satisfying results have been achieved in practical application.
