A Modified Method to Obtain Excitation Functions of J-K Flip-flops

针对由状态转移关系求取J-K触发器激励函数的传统方法存在的问题,通过分析状态转移表和J-K触发器的特性方程的内在联系,给出一种由状态转移表直接获取J-K触发器激励函数的方法.该方法能有效简化激励函数求取的过程,不需要太多的函数变换技巧,同时通过该方法得到的激励函数具有最简形式.

Aiming at the problems to obtain excitation functions of J-K flip-flops by its state transition relation,and based on the analysis for intrinsic relation between state transition table with characteristic equation of J-K flip-flops,the paper gives a modified method to obtain excitation functions which can efficiently simplify the process.Using this method,even if without too much skill for logic function transformation,one can directly obtain the excitation functions from the state transition table,and the excitation functions have simplest formal.
