State whether the following statements are true or false.
Statements:
(i) The JK flip-flop is a basic building block of combinational logic circuits.
(ii) In a ripple counter, if the uncomplemented output counts up, then the complemented output counts down.
- A.
(i) True, (ii) True
- B.
(i) True, (ii) False
- C.
(i) False, (ii) True
- D.
(i) False, (ii) False
Attempted by 71 students.
Show answer & explanation
Correct answer: C
Statement (i) is false because JK flip-flops are sequential elements with memory, unlike combinational circuits.
Statement (ii) is true because the complemented output Q' represents the inverse binary sequence, effectively counting down when Q counts up.
