While reviewing wireless survey reports, an intern asks a wireless engineer about the term noise floor. What is the definition of noise floor?
- Noise floor is the decreasing of the signal amplitude as it travels through free space.
- Noise floor is the average signal strength of the noise being received by a receiver.
- Noise floor is the maximum signal strength of the recorded noise received by a receiver.
- Noise floor is the smallest signal strength of the recorded noise received by a receiver.
| Explanation & Hint:
Noise is any other signal that is received on the same frequency as a signal of interest and noise floor is the average signal strength of that received noise. |
