🔍 Key Concepts

• Spread spectrum vs conventional modulation (like AM/FM) • Common spread spectrum methods: Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS) • Recognizing that some options list modulation formats, not spread spectrum techniques

💭 Think About

• Which choices list techniques specifically used to spread a signal over a wider bandwidth, rather than just modulate its phase, frequency, or amplitude? • Look at each option: which ones are you more likely to see associated with Wi‑Fi, Bluetooth, and older GPS-style links as spread spectrum methods? • Can a method like QPSK, QAM, or APSK be used inside a spread spectrum system, rather than being the spread spectrum technique itself?

✅ Before You Answer

• Before picking, be sure the two terms you select are both explicitly known spread spectrum types (not just general digital modulation schemes). • Verify that neither of your chosen terms is a basic analog modulation like AM/FM. • Check whether the pair you’re considering are usually mentioned together in textbooks or exam guides as the two classic spread spectrum techniques.
