🔍 Key Concepts

• Frequency modulation (FM) vs amplitude modulation (AM)** – what part of the RF signal is changed? • How class‑C RF amplifiers are normally modulated in high‑level modulation systems • What a balanced modulator is normally used for in communications (think: AM/SSB, not FM)

💭 Think About

• Ask yourself: to get FM, what part of the transmitter should the audio ultimately affect – the oscillator frequency or the amplifier supply voltage? • Which of these methods is typically associated with creating AM or SSB rather than FM? • Which choice describes changing the frequency of the RF signal at its source, instead of just changing its amplitude or power?

✅ Before You Answer

• Identify which option clearly relates to changing frequency at or near the oscillator, not just the output power level. • Eliminate any method you know is primarily used for amplitude modulation (AM) or single sideband (SSB). • Check that the remaining method would cause the carrier frequency to swing with the audio rather than its amplitude.
