基于知识处理的电路符号分析

A Knowledge-Based Symbolic Circuit Analysis Program

摘要: 本文介绍基于知识处理的电路符号分析程序SYMBANA.利用输入电路结构和符号参数,程序自动输出电路函数（例如,电压放大系数Av=v₀/vi）的符号公式和指定参数Pi的敏感度?Av/?Pi的符号表达式.SYMBANA运用知识处理技术和演绎方法,进行电路符号公式和参数敏感度的推导.SYMBANA是用micro-prolog写成,运行于IBM PC/XT,AT及各种兼容机.SYMBANA可用于各种电路分析、优化设计和计算机辅助学习.

Abstract: A knowledge-based symbolic circuit analysis program-SYMBANA is introduced.With inputs and symbolic parameters,the program outputs the symbolic expression of the circuit function such as voltage gain Au=Vo/Vi and the symbolic expression of sensitivity(?Av/?pi)for given parameter(pi).Written in micro-prolog,SYMBANA uses knowlege processing and inference.It can be run on IBM PC/XT,AT and their compatible computers.SYMBANA can be used as CAD/CAI tool in electronic field.
