The lower the receiver noise figure becomes, the greater will be the receiver's _________:
- A rejection of unwanted signals
- B selectivity
- C stability
- D sensitivity
Correct answer: D — sensitivity. From the official ISED question bank, verified word for word.
Why
A lower noise figure means the receiver adds less static of its own, allowing it to hear very faint signals that would otherwise be lost in the background hiss. The full explanation — and one for every question — is in Pro.
