What is the definition of detection in a radio receiver?

🔍 Key Concepts

• Detection stage of a radio receiver • Difference between modulation and demodulation • How intelligence (audio/data) is carried on a radio-frequency (RF) carrier

💭 Think About

• In a receiver, at what point do we get back the original audio or information from the RF signal? • Which option describes removing or extracting information, rather than adding it to the carrier? • Which choices clearly describe receiver functions that are NOT related to recovering the wanted information?

✅ Before You Answer

• Verify which option talks about recovering intelligence/information from the RF signal. • Eliminate any options that describe adding information to a carrier (that is a transmitter function, not a receiver function). • Watch for choices that mention noise or meters rather than the wanted signal content; those are not the core definition of detection.

What is the definition of detection in a radio receiver?

The process of masking out the intelligence on a received carrier to make an S-meter operational.

The recovery of intelligence from the modulated RF signal.

The modulation of a carrier.

The mixing of noise with the received signal.
