Which of the following is a spread spectrum technique that employs mathematical algorithms to recover lost data bits?
A) frequency hopping
B) direct sequence
C) narrow band
D) wide band

Question

Quizplus · Accepted Answer

Direct sequence spread spectrum technique employs mathematical algorithms to recover lost data bits. Frequency hopping does not employ mathematical algorithms to recover lost data bits and only changes frequency channels. Narrow band and wide band refer to the range of frequencies used and do not necessarily involve data recovery techniques.
