Question

A flip-flop circuit can be used for

• A. Counting
• B. Synchronization
• C. Rectification
• D. Demodulation

Hint:

Flip-flops are fundamental components in digital electronics and are primarily used for counting, storing binary data, and timing applications.

Answer 1

The Correct Option is A

A flip-flop circuit is a basic digital memory circuit used to store a single bit of data. It can be used for counting, as it can store two stable states (0 and 1). By connecting multiple flip-flops together, they can be used to count in binary.
Thus, the correct use of a flip-flop circuit is for \( \text{Counting} \).
