引言在逻辑设计中如何运用最简便的方法,以最少的逻辑元件组成所需要的逻辑关系,是逻辑设计的基本任务之一。卡诺图就是实现这一任务的一种工具。卡诺图是将输入变量以一定规则排列构成和函数真值关系一一对应的方格图表。本文将探讨卡诺图的几种用法。包括多端输出的卡诺图、如何应用卡诺图设计逻辑线路、计数器及多相步进电机的可逆循环控制逻辑。 Introduction It is one of the basic tasks of logic design to use the simplest method in logic design and to compose the required logic relationship with a minimum number of logic elements. Carnot map is a tool to achieve this task. Carnot map is the input variable to a certain rule arranged and the relationship between the true value of the function one by one corresponding to the grid chart. This article will explore several uses of Karnaugh map. Including Karnaugh map of multi-output, how to apply Karnaugh map design logic circuit, counter and reversible cycle control logic of multi-phase stepping motor.
