*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 by sending color lines sequentially. This method involves transmitting each line of the image one after the other, with the color information encoded within each line. Here's why the correct answer is correct and why the other choices are incorrect:

1. **Correct Answer: Color lines are sent sequentially (Choice A)**
   - In analog SSTV, each line of the image is sent one at a time, and the color information is encoded within these lines. This sequential transmission allows the receiving station to reconstruct the image line by line, including the color information.

2. **Why the Other Choices are Incorrect:**
   - **Choice B: Color information is sent on a 2.8 kHz subcarrier**
     - This is incorrect because SSTV does not use a subcarrier for color information. Instead, the color is directly encoded in the signal of each line.
   - **Choice C: Color is sent in a color burst at the end of each line**
     - This is incorrect because SSTV does not use a color burst method like NTSC television. The color information is integrated into the line signal itself, not sent as a separate burst.
   - **Choice D: Color is amplitude modulated on the frequency modulated intensity signal**
     - This is incorrect because SSTV does not use amplitude modulation for color. The color is part of the frequency-modulated signal that represents each line.

In summary, the correct method for transmitting color in analog SSTV is by sending color lines sequentially, allowing the receiving equipment to decode and display the image with its color information intact.
