🔍 Key Concepts

• Beat Frequency Oscillator (BFO) function in radio receivers • How SSB (Single Sideband) signals are demodulated • Difference between carrier, sidebands, and what is present/missing in an SSB signal

💭 Think About

• Think about what is missing in an SSB signal compared to a full AM (A3E) signal and what you need in order to recover intelligible audio. • Ask yourself: does the BFO operate in the transmitter, the receiver, or both? How does that affect which option can be true? • Consider which option describes something that happens at the detector stage of a receiver handling SSB.

✅ Before You Answer

• Identify which choice talks about adding a frequency at the receiver detector rather than changing the transmitted signal itself. • Check which options claim the BFO is removing or replacing parts of the transmitted signal — is that really what an oscillator in the receiver does? • Verify that the correct option must describe generating a beat between a locally generated frequency and the incoming SSB signal to recover audio.
