The dynamic range is the ratio of the smallest to the largest ________ that a system can process without distortion.

• A. Phase delay
• B. Frequency
• C. Spatial length
• D. Amplitude

Answer: (D)

Dynamic range is about the span of signal levels a system can handle in a linear way. It’s the ratio, usually expressed in dB, between the smallest usable signal amplitude and the largest undistorted signal amplitude that the system can process. The smallest amplitude is set by the noise floor and sensitivity, while the largest is set by saturation or nonlinear distortion. That’s why the term that fits is amplitude. Phase delay, frequency, and spatial length describe timing, spectral content, or geometry, not how wide a system’s linear operating range is.
