Updated On: Nov 25, 2025
- is a divide-by-5 counter
- is a divide-by-7 counter
- is a divide-by-8 counter
- does not function as a counter due to disjoint cycles of states
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the digital circuit.
This circuit consists of D flip-flops connected with a feedback loop, with the clock signal driving the flip-flops. The feedback mechanism determines how many clock pulses are required for the system to complete a cycle. The output of each flip-flop will represent a binary count, and based on the feedback configuration, the system will divide the clock by a certain factor. Step 2: Analyzing the options.
- (A) Correct, based on the circuit configuration, the feedback loop will result in a divide-by-5 counter.
- (B) Incorrect, the counter does not divide by 7 based on the given configuration.
- (C) Incorrect, this is not a divide-by-8 counter based on the feedback loop.
- (D) Incorrect, the counter functions as expected and does not have disjoint cycles. Step 3: Conclusion.
Thus, the correct answer is (A).
