ABSTRACT
This paper introduces an universal way on how to design and produce the digital circuit system, analyses the branch circuits, and divides the complex system into different unit systems which are separate relatively and in different layers. From the analysis of the units logical architecture, it chooses different suitable IC digital circuit implements to achieve the general purpose. And last uses many digital circuit implements to execute various complex logical relations.
Digital electronic clock is a digital circuit to indicate seconds, minutes and hours of time device, with the traditional mechanical bell, it has walking accurate, visual shows, no mechanical transmission equipment, and other advantages, so it has become widely used. Digital electronic clock consists of the following components: quartz crystal oscillator and divider comprising seconds pulse generator; School circuit; reset the device; 6 decimal seconds-counter, 24 hours at the counter; and the seconds, minutes and decoding the part of such shows.
Key words: Digital Circuit, System Design, Produce, Digital Clock
