🔍 Key Concepts

• FM (Frequency Modulation) vs AM (Amplitude Modulation) detection • What part of a receiver actually recovers the audio/information from a modulated RF signal • Difference between generating a signal and detecting or filtering a signal

💭 Think About

• Ask yourself: in an FM receiver, which block converts changes in frequency of the incoming RF/IF signal into changes in amplitude (audio) that you can hear? • Which option describes a circuit whose job is specifically to respond to frequency variations, not to produce them or to separate nearby channels? • Eliminate choices that describe functions done before detection (like channel selection/filtering) or in the transmitter (signal generation)

✅ Before You Answer

• Verify which choice explicitly mentions FM signals and their detection or demodulation. • Check that you are not confusing filtering (selecting channels) with demodulation (recovering the information). • Confirm that a generator is normally associated with a transmitter, while a discriminator/detector is associated with a receiver.
