🔍 Key Concepts

• How regenerative receivers use feedback to increase gain and sensitivity • The difference between no/low feedback, incorrectly phased feedback, and a component failure like a faulty tube • How each of the listed issues would affect the receiver’s sensitivity

💭 Think About

• For each option, ask: Would this condition reduce how well the receiver can pick up weak signals? How? • Think about what out of phase feedback does compared with insufficient feedback in a circuit designed to regenerate (reinforce) signals. • Consider whether one, two, or all three of these problems could realistically cause low sensitivity in a regenerative receiver.

✅ Before You Answer

• Make sure you understand that sensitivity is about detecting weak signals, not selectivity or distortion. • Check whether both insufficient feedback and wrong-phase feedback would reduce the amplification effect of regeneration. • Ask yourself if a faulty tube in any of the 3 stages could also result in weak overall signal strength (low sensitivity).
