- Low pass filtering
- Periodic sampling
- Quantizing
- Companding
- Amplitude modulation
Correct answer: E
Question 9
The signal at the input to a balanced twisted pair cable is 10 mW. The cable is 1000 feet long and has an attenuation of 1 dB per 100 feet. This cable is connected to the input of a receiver.

- 10 dB
- 30 dB
- 40 dB
- 60 dB
- 100 dB
Correct answer: B
Question 10
You must place CAT6 cable above a factory floor with automated welding machines and hammer forges. Of the following, what type of shielding would be most effective?
