摘要
针对某些控制系统,给出一种校正系统时间偏差的延时电路。利用74LS160十进制计数器、555定时器等器件和数字电子技术完成电路的设计,并给出了电路中器件参数设定的原则。
This article introduces one delay electro-circuit to mend system time errors. Design of the electro-circuit depends on devices such as 74LS160 decimal system calculation and 555 timer, together with digital electro technology, in addition, principle to set parameters in electro-circuit has been described.
