Question

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Master-slave J-K flip-flop is free from race around condition. Reason (R): Master-slave uses two J-K flip-flops. In the light of the above statements, choose the most appropriate answer from the options given below :

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Race-around condition occurs in JK flip-flops when: \[ J=K=1 \] Master-slave configuration removes this problem by using two cascaded flip-flops operating on opposite clock phases.

Answer 1

The Correct Option is A
