🔍 Key Concepts

• Function of AFC (Automatic Frequency Control) in a RADAR receiver • Role of each stage: mixer, detector, and discriminator in superheterodyne radar receivers • How a radar receiver develops a control voltage to correct frequency errors

💭 Think About

• Which type of circuit is specifically designed to produce a control (error) voltage that varies with frequency offset from the desired value? • Among the choices, which circuits are primarily used for amplitude detection versus frequency/phase detection? • How does the radar system sense that the local oscillator or received signal is off frequency and generate a voltage to pull it back on frequency?

✅ Before You Answer

• Identify which device is associated with frequency discrimination rather than simple amplitude detection • Confirm which stage in a superheterodyne receiver actually produces an AFC control voltage, not just an intermediate frequency (IF) signal • Eliminate any options whose main job is mixing or envelope (AM) detection, rather than detecting frequency error
