在计算机、自动控制领域,逻辑函数的分析、变形和简化是一项基本而重要的工作。对于较复杂的逻辑函数,直接用布尔代数的基本公式化简,往往带有较强的经验性和盲目性,这样“卡诺图”就显出其特有的优越性。四变量及四变量以下的卡诺图已经相当成熟了,本文则着重探讨四变量以上的逻辑函数的图解分析方法,该方案是将多变量逻辑函数化整为零、各个击破,并找到了 In the field of computer and automatic control, the analysis, deformation and simplification of logic functions are a basic and important task. For more complex logic functions, the direct use of Boolean algebra basic formula simplification, often with a strong empirical and blind, so “Carnot map” shows its unique superiority. The four-variable and four-variable following Carnot map has been quite mature, this article focuses on the four variables above the logical function of the graphical analysis method, the program is to multivariate logic function into zero, each break, and found
