我们试制的MOS集成电路石英数字钟,已安装在邮电营业厅内。它一方面向用户显示准确的时间;另一方面还可以利用它作各种时序的自动控制。这种钟线路简单、维修方便、走时准确、显示美观。一、基本原理和电路元件整个数字钟用了十九块
Our prototype MOS integrated circuit quartz digital clock, has been installed in the post office. On the one hand it shows the user exactly the time; on the other hand it can also be used for automatic control of various timing. This bell line is simple, easy maintenance, travel time is accurate, beautiful. First, the basic principles and circuit components The entire digital clock with nineteen
