Without the delay time, each counter powers up with a random output count such that several LEDs may be on.

没有延时时间，每个计数器上电后，计数输出是随机的，这样若干LED也许是亮的。

This paper introduces a very practical circuit which can perform both the random pulse accumulative segmented time-delay and single time-delay.

实现了一种既能对随机性脉冲进行累计性分段延时，亦可进行单一时间延时的电路，实用性较好。
