Apart from sensitivity and selectivity, which of these is the third main indicator of communications receiver performance?
- A Frequency range
- B Fidelity
- C Volume range
- D Dynamic range
Correct answer: D — Dynamic range. From the official ISED question bank, verified word for word.
Why
Dynamic range measures a receiver's ability to handle both very weak and very strong signals at the same time without distortion or blocking, making it the third key performance indicator alongside sensitivity and selectivity. The full explanation — and one for every question — is in Pro.
