Question

The \(555\) timer in monostable mode produces

• A. Continuous square wave
• B. Single pulse
• C. Triangular wave
• D. Sawtooth wave

Hint:

Modes of a \(555\) timer: \[ \boxed{ \begin{aligned} \text{Monostable} &\rightarrow \text{Single pulse} \text{Astable} &\rightarrow \text{Continuous square wave} \text{Bistable} &\rightarrow \text{Two stable states} \end{aligned} } \]

Answer 1

The Correct Option is B

Step 1: Recall the operation of a monostable multivibrator. A monostable multivibrator has - one stable state, - one quasi-stable state.

Step 2: Identify the output. When triggered, the \(555\) timer switches to the quasi-stable state for a fixed duration and then returns to its stable state. Thus, it produces \[ \boxed{\text{A single output pulse}.} \] Therefore, \[ \boxed{(B)} \] is the correct answer.
