hello!
anyone one can provide me with the design of 12-hour digital clock using synchronous decade counters and truncated sequence counters to count minutes and seconds up to 59 and then reset?
 

Check out this site, i guess that's what you are looking for **broken link removed**
 

hello

This design is a TTL based implementation of a digital
clock, complete with hour and minute set buttons. The circuit
uses synchronous decade counters with appropriate gating to
implement each divider stage.



best regards.
