What is the term used for the decibel difference (or ratio) between the largest tolerable receiver input signal (without causing audible distortion products) and the minimum discernible signal (sensitivity)?

  1. ADynamic range
  2. BDesign parameter
  3. CStability
  4. DNoise figure

Correct answer: A — Dynamic range. From the official ISED question bank, verified word for word.

Why

Dynamic range measures the span between the faintest signal a receiver can hear and the loudest signal it can handle before distorting, essentially defining how well the radio copes with both weak and strong stations at once. The full explanation — and one for every question — is in Pro.
