🔍 Key Concepts

• Nature of static and lightning noise in radio communications • Difference between amplitude modulation (AM) and frequency modulation (FM) • How random noise shows up on a receiver that is set to AM vs FM

💭 Think About

• When you hear lightning crashes or static on a radio, what changes in the signal that your ear actually notices: the strength of the signal or its tuned frequency? • Think about which type of modulation is more easily affected by sudden spikes in signal strength. • On a typical marine VHF set, which mode (AM or FM-like) tends to "quiet" background noise better, and what does that suggest about the type of modulation in static?

✅ Before You Answer

• Be clear on what modulation means: what part of the radio wave is being varied to carry information. • Focus on how random spikes in signal strength from lightning or static would appear in terms of modulation. • Eliminate the harmonic frequencies options by asking: are lightning and static limited to only odd or only even harmonics, or do they spread broadly across frequencies?
