Sound produced by a tining fork is a sort of :-

Options

A. digital signal
B. analog signal
C. both (1) and (2)
D. neither (1) nor (2)

Answer

To determine the type of signal produced by a tuning fork, we can follow these steps:

### Step 1: Understand the Concepts of Analog and Digital Signals
- **Analog Signal**: An analog signal is characterized by continuous variation. The voltage (or current) can take any value within a given range, and it changes smoothly over time. The graph of an analog signal typically shows a continuous wave-like pattern.

- **Digital Signal**: A digital signal, on the other hand, consists of discrete values. It can only take specific levels (like high or low, 1 or 0) and does not vary smoothly. The graph of a digital signal appears as a series of square waves.

### Step 2: Analyze the Sound Produced by a Tuning Fork
- When a tuning fork vibrates, it produces sound waves that are continuous and vary in amplitude and frequency over time. The sound waves can be represented as a smooth waveform, which indicates that the signal is not discrete.

### Step 3: Conclusion
- Since the sound produced by a tuning fork varies continuously with time, it is classified as an **analog signal**.

### Final Answer
The sound produced by a tuning fork is an **analog signal**.
