PC2: Signal-to-Noise Ratio and Forward Error Correction Flashcards
1
Q
Compares the level of desired signal to the level of background noise
A
Signal-to-Noise Ratio (SNR)
2
Q
A rate at which a transmitted segment of data is received with incorrect bits as compared to the original message
A
Bit Error Rate (BER)
3
Q
A common means of encoding data to determine if any errors have been introduced to the message through channel noise, interference, or other source
A
Error Detection
4
Q
Identify
Resiliency through redundancy
A
Error Detection
5
Q
A method of adding redundant information to a data stream that allows for identification and correction of errors, and thus reduces or eliminates the need for retransmission
A
Forward Error Correction (FEC)
6
Q
FEC increases what?
A
The amount of bandwidth (BW) required
