Logic Diagram Of A 12 Hour Digital Clock. We have a total of 12 outputs. I hope this makes sense but this is the best i can do translating digital logic to the english language.
1 hz clock generator to generate 1 pps pulse per second signal to the seconds block. Our proposed project uses a ver y. The digital clock circuit was implemented and simulated using proteus software version 86 on personal computer pc.
Homemade ttl circuit 24 hour digital clock.
The 7410 triple input nand gate is used to decode the 13th hour from the 7493 and the remaining gates in the ic are used as inverters. The digital clock circuit was implemented and simulated using proteus software version 86 on personal computer pc. The previous pictures show the process of making it over the course of about a month. The 7485 and 74157 selects between the 7493 0 to 9 oclock and the 7490 10 to 12 oclock.
