How many sidebands does a VHF FM transmitter have?

If the question has a related picture, it will appear here.

🔍 Key Concepts

• Difference between AM (amplitude modulation) and FM (frequency modulation) in terms of sidebands • How modulation type affects the number of distinct sidebands • Whether VHF marine radios use narrowband FM for voice communications

💭 Think About

• Think about what a sideband actually is and how it is created when you modulate a carrier with audio • Recall whether FM produces a fixed small number of sidebands or a broader spectrum of many frequency components • Compare how many discrete sidebands are produced in simple AM voice transmission versus FM voice transmission

✅ Before You Answer

• Be clear on whether the question is asking about AM or FM – they behave differently • Remember that FM with voice modulation spreads the signal over multiple frequency components, not just a single upper and lower sideband • Before choosing, decide if the spectrum of an FM signal looks like just one, two, or multiple side frequencies around the carrier
