In order of selectivity, the best receivers are:

🔍 Key Concepts

• Selectivity in radio receivers (ability to separate one signal from nearby frequencies) • Basic characteristics of superheterodyne, tuned radio-frequency (TRF), and superregenerative receivers • Tradeoff between sensitivity and selectivity in different receiver designs

💭 Think About

• Think about which receiver design is typically used in high‑quality communications equipment when you need to clearly separate closely spaced channels. • Which receiver type is known to be very simple and very sensitive, but is also quite noisy and poor at rejecting nearby signals? • Between TRF and superheterodyne, which one offers more stable, sharper tuning across a wide frequency range?

✅ Before You Answer

• Be clear on the definition of selectivity (it is not the same as sensitivity). • Rank the three receiver types from best to worst selectivity based on their typical real‑world use in communications gear. • Eliminate any option where the noisier, less selective design is placed ahead of the more complex, higher‑performance design.
