基于阈值逻辑门的对称函数的综合

The Synthesis of Symmetric Functions Based on Threshold-Logic Gates

阈值逻辑门是一种逻辑功能很强的逻辑电路，任意线性可分离函数只要用一个单阈值逻辑门便可予以实现，本文讨论与分析了阈函数、对称函数的有关性质，指出了任意对称函数可以方便地用具有多阈值、多输出的阈门及异或门予以实现，文中给出了相应的综合程序．

The threshold logic gate is a kind of logic circuit having very powerful logic function. An arbitrary linear-ly separable function can be realized by a single-threshold logic gate. This paper discusses and analyzes theprocedure of threshold functions and symmetric functions,and points out that any symmetric function may beeasily realized by a threshold logic gate with multi-threshold and multi-output and Exchsive-OR gates. Thecorresponding synthesis procedure is given in this paper.
