Which statement describes noise jamming?

Which statement describes noise jamming?

• A. Modulation of incoherent to random pattern of bits that does not contain data
• B. Modulation of a signal with intelligible data that can be broken out and interpreted
• C. Using a narrowband sweep across the band
• D. Coherent jamming of a signal to mask data

Answer: (A)

Noise jamming works by filling the channel with a random, noise-like signal that carries no information. The best description is transmitting a random pattern of bits that does not contain data, which creates incoherent interference that looks like noise and degrades the received signal across the band. This differs from adding a signal with intelligible data, which would be a real transmission, and from coherent or narrowband jamming tactics that rely on phase alignment or targeted frequencies rather than broad, random noise.
