🔍 Key Concepts

• How a regenerative receiver uses feedback to increase gain • The role of positive (in‑phase) feedback between plate and grid circuits • The normal path of a signal in a basic RF amplifier stage (grid → plate)

💭 Think About

• First, ask yourself what happens to an RF signal when it enters the grid circuit of a tube in a simple receiver. Which option(s) describe that basic process? • Next, think about what makes a receiver specifically regenerative: what extra step happens with the plate signal, and how does that affect the grid circuit? • Finally, consider whether regeneration involves only one of these steps, or whether all described steps must occur together for true regenerative operation.

✅ Before You Answer

• Check which choices correctly describe: (1) how the RF carrier is applied to the grid, (2) how it is amplified, and (3) how feedback is returned from plate to grid. • Verify that regenerative action requires the feedback signal to be in phase (positive feedback) with the original signal to increase gain. • Before selecting, ask: does any single choice omit a key part of regenerative operation, or is there an option that combines all necessary steps?
