A general rule is that the chip rate is what relative to the data modulation rate?
A) must be less that 12% of the modulation rate
B) approximately 5 to 7 times the modulation rate
C) is independent of the modulation rate
D) must be greater than 70.7% of the modulation rate

Question

Quizplus · Accepted Answer

The chip rate in spread spectrum technologies, such as CDMA, is typically higher than the data modulation rate to effectively spread the signal over a wider bandwidth. This spreading allows for better resistance to interference and eavesdropping. A common range is 5 to 7 times the modulation rate, though the exact factor can vary depending on the specific technology and implementation.
