The process of separating radio signal from the modulated wave is known as

Options

A. Superimposition
B. Amplification
C. Demodulation
D. Modulation

Answer

To solve the question, we need to identify the process of separating the radio signal from the modulated wave. Let's break it down step by step:

### Step-by-Step Solution:

1. **Understanding Modulation**:
- Modulation is the process where the properties of a high-frequency carrier wave are altered according to the information signal (the message we want to transmit). This is typically done to enable the transmission of the signal over long distances.

2. **Identifying the Components**:
- The two main components involved are:
- **Carrier Signal**: A high-frequency wave that carries the information.
- **Modulating Signal**: The actual information or message that is to be transmitted.

3. **Receiving the Modulated Signal**:
- When the modulated signal is transmitted and received, it contains both the carrier wave and the modulating signal.

4. **Need for Separation**:
- To retrieve the original message (the modulating signal), we need to separate it from the modulated wave. This process is crucial for understanding the information that was sent.

5. **Defining Demodulation**:
- The process of extracting the original modulating signal from the modulated carrier wave is known as **demodulation**. This is the reverse process of modulation.

6. **Conclusion**:
- Therefore, the correct answer to the question "The process of separating radio signal from the modulated wave is known as" is **demodulation**.

### Final Answer:
The process of separating radio signal from the modulated wave is known as **demodulation**.
