🔍 Key Concepts

• Meaning of AGC in radio electronics (what each letter stands for) • How a receiver handles strong vs. weak signals to keep audio comfortable to listen to • Difference between AF (audio frequency) and RF (radio frequency) stages in a radio

💭 Think About

• First recall what AGC actually does to the overall audio volume when the received signal strength changes—does it keep it steady, raise it, or lower it? • Think about whether AGC acts mainly on the RF stages, the AF stages, or on the listener’s perceived volume. • Look at which options describe a behavior that works both for strong and weak signals, rather than only one condition.

✅ Before You Answer

• Be sure you know that AF = audio frequency (what you hear) and RF = radio frequency (the received radio signal itself). • Check which option describes an action that automatically stabilizes what you hear at the speaker instead of simply boosting or cutting under one condition. • Eliminate any choice that only makes sense when the signal is strong but not when it is weak (or vice versa); AGC should work over a range of signal strengths.
