🔍 Key Concepts

• Receiver noise sources in superheterodyne receivers • Role of the first RF / input stages compared to later audio-frequency (AF) stages • How amplification early in the chain affects total noise heard in the speaker

💭 Think About

• Which stage’s noise will be amplified the most by ALL the following stages, and therefore be heard as hiss? • Is hiss more closely associated with RF/IF stages or with audio-frequency amplification and detection? • Would a control related to oscillation/regeneration normally be the primary cause of typical background hiss in a correctly operating receiver?

✅ Before You Answer

• Identify which stage is earliest in the signal chain among the options • Think about which choice describes a normal internal noise source, not a fault condition • Ask whether the remaining options would usually cause distortion/instability rather than steady broadband hiss
