What is digital clock and how it works?

How does a counter work in a digital clock?

Electronic counters. An electronic counter is a sequential logic circuit which has a clock input signal and a group of output signals that represent an integer "counts" value. Upon each qualified clock edge, the circuit will increment (or decrement, depending on circuit design) the counts.

How do you make a digital clock with a counter?

Divide by 10 Counter

1. In order to use all 4 bits of the counter, Q0 must be connected to CP1.
2. The input clock is connected to CP0.
3. To implement a divide by 10 or MOD10 counter, Q1 is connected to MR1 and Q3 is connected to MR2.
4. The output frequency at Q3 is the input clock frequency divided by 10.
