摘要: 本文利用幾個(gè)定義和限制,得到了一外部激勵(lì)x,n個(gè)狀態(tài)變量電位異步時(shí)序電路的任一狀態(tài)的一般邏輯表達(dá)式特性方程.將此方程與狀態(tài)表結(jié)合,導(dǎo)出了產(chǎn)生時(shí)序險(xiǎn)象時(shí)的狀態(tài)變量數(shù)和穩(wěn)定狀態(tài)數(shù)所滿足的條件;給出了對(duì)時(shí)序險(xiǎn)象研究特別有用的基本判定法則.

Abstract: By using some definitions and restrictions, an ordinary logical expression-the characteristic equation for one external urge and an orbitrary state of n-state variables potential asynchronous sequential logical circuit is obtained. The characteristic equation combines express with the state table, the conditions satisfied by the state variable numbers and stable state numbers when happen sequential hazards are deduced. The basic laws which are particularly used to study sequential hazards are given. -
