Hi, I am writing a report on making a logical circuit for a 24 hour digital alarm clock which rings every 45 mins. How it is set up is that I have the power supply hooked up to the pulse generator which is connected to the second section. The second section is connected to the minute section and the minute section is connected to the hour section. My second section and minute section has the DB10 and DB6 decoder which I understand makes a counter which counts from 0 to 59 seconds. However, I am a bit confused on how to make my hours section. Should I have a DB3, DB5 and a DB10 to make 0-23 or do I just have a DB3 and DB5. This is because from what I understand, if I only have the DB3 and DB5, a the minute section will be connected to the DB5 which will count up to 4 before recycling while initiating the DB3 to count to 2. If this happened wouldn't it make the hour section only count up to 8 hours in total?
The former option makes more sense to me but I am still confused on how to set it up...
Thank you
