🔍 Key Concepts

• A2 emission meaning (carrier plus modulated tone telegraphy) • Relationship between modulating frequency and resulting sidebands • How total bandwidth is calculated from the highest and lowest significant frequencies

💭 Think About

• Think about what frequency components are created when an 800 Hz tone modulates a 500 kHz carrier in A2 emission. Where are the sidebands located relative to the carrier? • If you know the spacing of the sidebands from the carrier, how far apart are the highest and lowest significant frequencies in hertz? • How do you convert between hertz and kilohertz, and which answer choices are actually the same value written in different units?

✅ Before You Answer

• Identify the upper and lower sideband frequencies around the 500 kHz carrier when using an 800 Hz tone • Compute the difference between the highest and lowest frequency components to get total bandwidth • Double‑check unit conversion: 1 kHz = 1000 Hz, and make sure you’re not confusing carrier frequency with bandwidth
