Question 1 of 27070

What term describes a wide-bandwidth communications system in which the RF carrier frequency varies according to some predetermined sequence?

🔍 Key Concepts

• Spread spectrum communication and how it uses a changing (hopping) RF carrier frequency • The basic idea of frequency modulation schemes in the time domain • How narrow-band versus wide-band systems differ in bandwidth usage

💭 Think About

• Which option explicitly suggests a system where the carrier frequency itself is intentionally varied following a pattern? • Which terms in the choices are you familiar with from other questions (e.g., SITOR, SSB) and do they normally involve a fixed or changing carrier frequency? • Think about which technique is commonly associated with resistance to interference and jamming by spreading the signal over a wider frequency range.

✅ Before You Answer

• Identify which choice is known to be a wide-band, interference‑resistant technique. • Eliminate options that describe narrow‑band or single‑channel modes rather than frequency‑hopping or spreading. • Double‑check the definition of SITOR and single sideband (SSB) to see if they match the idea of a hopping RF carrier.
