Decrease in signal strength due to energy losses is called

Options

A. Distortion
B. Interference
C. Atienuation
D. Noise

Answer

To solve the question, "Decrease in signal strength due to energy losses is called," we will analyze the provided terms and their definitions step by step.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the term that describes the decrease in signal strength specifically due to energy losses.

2. **Identifying the Options**: The options provided are:
- Distortion
- Interference
- Attenuation
- Noise

3. **Defining Each Term**:
- **Distortion**: This refers to a change in the signal that alters its basic waveform. It does not specifically relate to energy loss.
- **Interference**: This is when unwanted signals modify the original signal in a disruptive manner. It does not directly relate to energy loss either.
- **Attenuation**: This term specifically refers to the loss of signal strength due to energy losses. This is the most relevant term to the question.
- **Noise**: This is defined as unwanted disturbances in an electrical signal, but it does not specifically refer to energy loss.

4. **Choosing the Correct Answer**: Based on the definitions, the term that best fits the description of a decrease in signal strength due to energy losses is **Attenuation**.

5. **Final Answer**: Therefore, the answer to the question is **Attenuation**.
