Question

Common application of flip-flops in digital circuits is:

• A. Amplification
• B. Signal generation
• C. Data storage
• D. Signal modulation

Hint:

Flip-flops = 1-bit memory cells. They're the backbone of digital data storage!

Answer 1

The Correct Option is C

Flip-flops are fundamental building blocks in digital electronics used primarily for data storage. A flip-flop can store one bit of data and maintain its output state until triggered to change by a clock or control signal.
They are extensively used in:

• Registers,
• Counters,
• Memory units,
• State machines.

Each flip-flop holds its binary state (0 or 1) stably and changes it only when instructed, making them ideal for synchronous data storage and sequencing.
Why the other options are incorrect:

• (A) Amplification is a function of analog components like transistors or op-amps.
• (B) Signal generation is handled by oscillators, not flip-flops.
• (D) Signal modulation relates to analog communication systems, not digital storage.

Thus, flip-flops are primarily used for storing binary data in digital systems.
