*Question E2B04:
How is color information sent in analog SSTV?*  

*Correct Answer is  A: Color lines are sent sequentially*  

### AI Response: (may contain errors)  

In analog Slow Scan Television (SSTV), color information is transmitted in a specific manner. Let's break down the correct answer and the other options.

### Correct Answer: A - Color lines are sent sequentially

- **Explanation**: In analog SSTV, each line of the image is transmitted one after the other. The color information for each line is encoded in a way that allows the receiver to reconstruct the full image by processing these sequential lines. This method ensures that the color and brightness information for each line is accurately represented.

### Why the Other Choices are Incorrect:

- **B: Color information is sent on a 2.8 kHz subcarrier**  
  - **Explanation**: While SSTV does use subcarriers for transmitting color information, the specific frequency of 2.8 kHz is not the primary method for sending color in analog SSTV. Instead, the color is integrated into the line transmission itself.

- **C: Color is sent in a color burst at the end of each line**  
  - **Explanation**: In SSTV, color information is not sent as a burst at the end of each line. Instead, it is embedded within the line data. A color burst is more commonly associated with other video transmission standards, such as NTSC.

- **D: Color is amplitude modulated on the frequency modulated intensity signal**  
  - **Explanation**: This statement is misleading. In SSTV, the intensity of the signal is typically frequency modulated, while color information is not simply amplitude modulated on this signal. The color is encoded in a way that is more complex than just amplitude modulation.

### Summary

- **Key Concept**: In analog SSTV, color lines are sent sequentially, allowing for the reconstruction of the image line by line.
- **Important Note**: Understanding how SSTV encodes and transmits color information is crucial for grasping the overall operation of this mode of communication.

This explanation should help clarify the method of color transmission in analog SSTV for your exam preparation.
