Master-slave flip flop consists of how many flip-flops:
- 4
- 3
- 1
- 2
Correct answer: 4. 2
Explanation: A master-slave flip-flop consists of two basic flip-flops: a master flip-flop and a slave flip-flop. These two flip-flops work together to synchronize the input signal and produce the desired output. The master flip-flop latches the input signal during the first phase of the clock cycle, and the slave flip-flop latches the output of the master flip-flop during the second phase of the clock cycle. This arrangement ensures that the output is stable and synchronized to the clock signal. Therefore, the correct option is 2 flip-flops.
