🔍 Key Concepts

• Function of a mixer stage in a superheterodyne receiver • Difference between detector stages and oscillator stages • Role of the beat frequency oscillator (BFO) in reception

💭 Think About

• Which stage combines the incoming RF signal with a locally generated oscillator signal to produce an intermediate frequency (IF)? • What is the primary job of a detector in a receiver, and how is that different from mixing frequencies? • Where in the signal chain would you expect the BFO to operate: during frequency conversion or during demodulation of CW/SSB signals?

✅ Before You Answer

• Identify which component actually mixes two frequencies to create new frequencies (sum and difference). • Confirm that a detector usually refers to recovering audio or information from a modulated signal, not converting it to an intermediate frequency. • Verify the specific purpose of the beat frequency oscillator in relation to CW/SSB reception rather than main RF-to-IF conversion.
