Which of the following are advantages of spread-spectrum versus narrowband transmissions? (Choose all that apply.)
A) resistance to outside interference
B) efficiency due to limited spectrum use
C) lower power requirements
D) increased security

Question

Quizplus · Accepted Answer

Spread-spectrum transmissions offer several advantages over narrowband transmissions, including resistance to outside interference (A), which makes them more robust in noisy environments. They also have lower power requirements (C) because the signal is spread across a wider bandwidth, making it less susceptible to interference and eavesdropping, which inherently increases security (D). However, they do not necessarily offer efficiency due to limited spectrum use (B); in fact, by spreading the signal over a broader spectrum, they use more bandwidth than narrowband transmissions.
