*Question G7C02:
What output is produced by a balanced modulator?*  

*Correct Answer is  D: Double-sideband modulated RF*  

### AI Response: (may contain errors)  

A balanced modulator is a device used in amplitude modulation (AM) systems that produces a specific type of output. Let's break down the question and the choices:

### Correct Answer: D - Double-sideband modulated RF

- **Explanation**: A balanced modulator takes an audio signal and a carrier signal and combines them to produce a double-sideband modulated (DSB) output. This means that both the upper and lower sidebands of the carrier frequency are generated, while the carrier itself is suppressed. The output consists of two sidebands that carry the information of the audio signal.

### Why the Other Choices are Incorrect:

- **A: Frequency modulated RF**  
  - **Explanation**: Frequency modulation (FM) involves varying the frequency of the carrier signal in accordance with the audio signal. A balanced modulator does not produce frequency modulation; it produces amplitude modulation.

- **B: Audio with equalized frequency response**  
  - **Explanation**: This choice suggests that the output is a processed audio signal. However, a balanced modulator does not output audio directly; it outputs a modulated RF signal. The audio signal is used to modulate the carrier, but the output is not simply audio.

- **C: Audio extracted from the modulation signal**  
  - **Explanation**: This choice implies that the output is the original audio signal. In reality, the balanced modulator combines the audio signal with the carrier, resulting in a modulated RF signal, not the original audio.

### Summary

- A balanced modulator produces a double-sideband modulated RF output, which is essential for AM transmission.
- The other options do not accurately describe the output of a balanced modulator, as they either refer to different modulation techniques or suggest outputs that do not align with the function of the device.

This understanding is crucial for grasping the principles of modulation in amateur radio and will help you in the Extra Class exam.
