On such as automatic stopping alarm, the bell, time program automatically automatic control, regular radio, automatic on-off circuit, timer switch oven, even various timing appliance automatic enabled, etc., all these, all based on automatic counters. Because of its powerful, versatility, convenient use, so in this electronic technology development era, it is a very good electronic products. Therefore, the automatic counters and expand its application, has a very realistic significance. This course is designed to test a theory study level,practical ability and practical ability,combining theory with certain requirements analysis and processing problem ability and self-educated abilities have a more important practical courses.Through this process,make our papers and practical level once relatively comprehensive examination,at the same time makes us the ability of hardware to improve,after learning has this very important significance.
