Dynamic Range

Measurement Span

Performance ratios describing signal processing instruments define the ratio between the largest linear signal a system can process and the smallest detectable signal above background noise. Measuring dynamic range quantifies the span over which an instrument maintains predictable output linear response without clipping or spectral masking. Decibel units express this parameter across electrical, optical, and acoustic domains.

High-resolution digitizers require low noise floors to achieve wide operational spans.

Noise Floor

System noise floors set absolute lower boundaries for weak signal detection. Thermal noise in input resistors and active amplifier flicker noise combine to generate continuous background spectral density. Signal detection below this background level requires long integration times or narrow filtering.

Distortion Ceiling

Harmonic distortion and amplifier saturation define the upper signal amplitude limit. Nonlinearities produce spurious spectral components when input voltages approach supply rails. Intermodulation products obscure small target signals in multi-tone environments.

Scale Ratio

Specification sheets express dynamic range using full-scale root mean square signal power divided by noise power. In digitizing systems, this value scales with bit depth according to six decibels per bit plus two decibels for ideal sine wave inputs. Thermal drift in voltage references reduces effective operational range across wide temperature spans.
