Samsung R&D Hardware Interview Questions, Process, and Tips

To divide the frequency of the clock by two, use a flip-flop circuit.

• Use a D flip-flop or a JK flip-flop.

• Connect the output of the flip-flop to the input of the clock signal.

• The output of the flip-flop will be half the frequency of the input clock signal.

To divide the frequency of the clock by three, use a counter with a divide-by-three function.

• Use a counter IC with a divide-by-three function

• Connect the clock signal to the counter input

• Use the output of the counter as the new clock signal

FSM stands for Finite State Machine. Mealy and Moore machines are two types of FSMs with differences in output.
