4.1简化的目的逻辑代数的函数一般都是在电子计算的线路中应用的,也就是用半导体二极管或三极管的线路来实现函数的表达式。因此,线路的成本和线路的简单与否与二极管或三极管元件的数目有极大的关系,而二极管或三极管元件的数目则与函数的简化有关。因此逻辑函数的最简化是为了求得最低的线路成本。本章主要介绍函数的变换和分解函数表达式的方法,以求得最简化的函数。所以是电子计算机和数字程序控制装置的逻辑线路设计的基础原理之一。
4.1 Simplify the purpose of the function of logic algebra are generally used in the calculation of electronic circuits, that is, the use of semiconductor diodes or transistors to achieve the function of the line. Therefore, the cost of the line and the simplicity of the line are strongly related to the number of diodes or triode elements, and the number of diodes or triode elements is related to the simplification of the function. Therefore, the most simplified logic function is to find the lowest line cost. This chapter introduces the function transformation and decomposition function expression method, in order to obtain the most simplified function. So it is one of the basic principles of logic circuit design of electronic computer and digital program control device.
