2.6.6 Attenuation& Interference Issues

Question 1

Card 1: Attenuation

Answer 1

Definition: The loss of signal strength as it travels through a medium (cable). Measured in decibels (dB).

Question 2

Card 2: Insertion Loss

Answer 2

Definition: (Same as attenuation) A measure of the signal loss in a cable, from transmitter to receiver.

Question 3

Card 3: Decibel (dB) Loss

Answer 3

A unit of measurement expressing the ratio between two values, typically signal strength at the source and at the destination, using a logarithmic scale.

Question 4

Card 4: Electromagnetic Interference (EMI)

Answer 4

Definition: Interference caused by electrical or magnetic fields from external sources.

Question 5

Card 5: Radio Frequency Interference (RFI)

Answer 5

Definition: A specific type of EMI that occurs in the frequencies used for radio transmissions.

Question 6

Card 6: Alien Crosstalk

Answer 6

Definition: Interference from signals in adjacent cables.
