基于四位全加器的开关函数加权实现

Weighted Realizations of Switching Functions Based upon Four-bit Full-adder

任意开关函数都可表示成某些变量重复的对称函数形式,即开关函数的加权表达式.本文根据开关函数的加权表达式,提出了基于四位全加器的加权网络的实现,并在此基础上通过使用数据选择器实现开关函数.

Any switching function can be expressed as a symmetric function form with some repeated variables, i.e. the weighted representation of a switching function. According to the weighted representation this paper proposes the realization of the weighted network by using four-bit full-adders. Based upon it, a switching function may be realized by means of a multiplexer.
