The following diagram represents a finite state machine which takes as input a binary number from the least significant bit 
Which one of the following is TRUE?
  • a)
    It computes 1’s complement of the input number.
  • b)
    It computes 2's complement of the input number.
  • c)
    It increments the input number.
  • d)
    It decrements the input number.
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
The following diagram represents a finite state machine which takes as...

Here, for state Q0
When input is 0 output is 0 and it remains in state Q0.
When input is 1 output is 1 and goes to state Q1.
For state Q1.
When input is 0 output is 1, when input is 1 output is 0.
Here state changes from Q0 to Q1 when there is a 1 as input, in state Q1 every input is complemented.
Hence, the given circuit computes 2’s complement of the input number.
Hence (b) is correct answer.
