Q1. How to devide to frequency of the clock using 3
Ans. 
To divide the frequency of the clock using 3, you can use a divide-by-3 counter circuit.
• Use a divide-by-3 counter circuit to divide the clock frequency by 3.

• Connect the clock signal to the input of the counter circuit.

• Obtain the divided clock signal at the output of the counter circuit.

• Example: If the input clock frequency is 12 MHz, the output frequency will be 4 MHz after dividing by 3.
