🔍 Key Concepts

• RF (radio frequency) vs audio frequency signals in a detector stage • Purpose of a filter in a tube circuit • What stages come after a detector in a typical receiver

💭 Think About

• In a detector, which type of signal do we want to keep sending to the next stages: RF or audio? • If RF leaks past the detector into later stages, what kind of problems could it cause? Distortion, instability, interference? • Think about whether a filter is normally used to pass or to block unwanted components. Which component is unwanted after detection?

✅ Before You Answer

• Identify which stages are normally placed after the detector in a receiver (RF, IF, or audio?). • Decide whether the filter in this position is meant to block RF or pass RF to what comes next. • Eliminate any choice that suggests adding unwanted RF into later stages instead of removing it.
