Q1. Write code of frequency divider
Ans. 
A frequency divider reduces the frequency of an input signal by a specified factor, often used in digital circuits.
• A frequency divider can be implemented using flip-flops.

• For example, a divide-by-2 circuit can be made with a D flip-flop.

• The output frequency is half of the input frequency.

• Frequency dividers are commonly used in clock generation.

• They can be cascaded to achieve higher division factors.

Q2. Difference between latch & flip flop
Ans. 
Latches are level-sensitive devices, while flip-flops are edge-sensitive, used for storing binary data in digital circuits.
• Latches are transparent when enabled, allowing data to pass through.

• Flip-flops change state only on specific clock edges (rising or falling).

• Example of a latch: SR latch, which can hold a state based on Set and Reset inputs.

• Example of a flip-flop: D flip-flop, which captures the input value on the ...read more
