Question

One example of the use of an S-R flip-flop is

• A. Transition pulse generator
• B. Racer
• C. Switch debouncer
• D. Astable oscillator

Hint:

S-R flip-flops are useful in applications like switch debouncing, where a clean, stable signal is required despite mechanical bounces in switches.

Answer 1

The Correct Option is C

An **S-R flip-flop** (Set-Reset flip-flop) is commonly used as a **switch debouncer**. When used in this way, it removes noise caused by the mechanical bouncing of a switch. The switch press generates a pulse, which is debounced by the flip-flop to produce a clean output. Therefore, the correct answer is option (3).
