*Question T4B10:
Which of the following receiver filter bandwidths provides the best signal-to-noise ratio for SSB reception?*  

*Correct Answer is  C: 2400 Hz*  

### AI Response: (may contain errors)  

To determine the best receiver filter bandwidth for SSB (Single Sideband) reception, we need to consider how bandwidth affects the signal-to-noise ratio (SNR).

### Correct Answer: 2400 Hz

1. **Why 2400 Hz is correct:**
   - SSB signals typically have a bandwidth of about 2.4 kHz. A filter bandwidth that closely matches the signal's bandwidth allows the desired signal to pass through while effectively rejecting noise and interference outside this range.
   - A bandwidth of 2400 Hz provides a good balance between allowing the full signal to be received and minimizing noise, thus maximizing the SNR.

### Why the other choices are incorrect:

2. **Choice A: 500 Hz**
   - A 500 Hz filter is too narrow for SSB signals, which can lead to distortion and loss of information. It may filter out important parts of the signal, resulting in a lower SNR.

3. **Choice B: 1000 Hz**
   - While a 1000 Hz filter is wider than 500 Hz, it is still too narrow for typical SSB signals. It may not capture the full signal bandwidth, leading to a compromised SNR.

4. **Choice C: 2400 Hz**
   - This is the correct choice, as explained above.

5. **Choice D: 5000 Hz**
   - A 5000 Hz filter is too wide for SSB reception. It allows too much noise and interference to pass through, which can degrade the SNR significantly.

### Summary:
- For optimal SNR in SSB reception, the filter bandwidth should closely match the signal's bandwidth, which is around 2400 Hz. This allows for effective signal reception while minimizing noise interference. 

### Rule of Thumb:
- Use a filter bandwidth that is approximately equal to the bandwidth of the SSB signal (around 2400 Hz) for the best SNR.
