🔍 Key Concepts

• Spread spectrum communication methods • Difference between frequency domain vs time/phase domain techniques • Meaning of a pseudo-random list of channels in radio communications

💭 Think About

• Ask yourself: which option specifically describes a system that rapidly changes the carrier frequency among many channels? • Consider: which terms are commonly paired together when listing types of spread spectrum (e.g., two classic families often taught together)? • Think about whether the description is about changing the data coding on one frequency, or actually jumping between multiple frequencies.

✅ Before You Answer

• Identify which choice explicitly suggests changing frequencies/channels rather than spreading a single carrier with a code sequence. • Recall the two basic spread spectrum types typically tested: one based on hopping frequencies, and one based on a continuous wideband code on one channel. • Eliminate any answer whose wording you have never seen associated with standard spread spectrum types in typical exam prep materials.
