Question

1. Repeaters are often used on both analog and digital communication systems to eliminate noise.

True

false

2. When determining the decibel value of the signal-to-noise ratio (SNR), both the signal and noise floor power must be referenced to the same power units (i.e., both referenced to 1 watt or 1 milliwatt, etc.).

True

False

3. Select the correct statement(s) regarding delay skew.

a. delay skew impacts all conductive guided mediums (e.g., UTP, coaxial cable, etc.)

b. delay skew only impacts fiber optic cables, since various wavelengths of light reach the c. delay skew impacts UTP and results in signal copies reaching the receiver at slightly different times based upon the twist ratio of each wire pair

detector at slightly different times

d. all statements are correct

Answer 1

Answer 1-

The correct Answer is — False

Explanation:

• Repeaters take away the unwished noise in an entering signal with analogue communication and it is beef up with amplifiers.

Answer 2-

The correct Answer is — True

Explanation:

• It's influencing the signal-to-noise ratio and necessity control that signal and noise power are in same units.

Answer 3-

The correct Answer is — option B

Explanation:

• Basically, delay skew solely bear on the fiber optic cables and effects to UTP and terminations in communication copies with the ranging of receiver.
