Amplitudmis

Amplitudmis is a term used in theoretical discussions of signal behavior and perception to describe a proposed measure of how amplitude fluctuations in an input signal influence a system’s output. It is not an established quantity in standard engineering or cognitive science and has no universally accepted definition.

The label combines the word for amplitude with a suffix that signals a substantive concept. In speculative literature, amplitudmis is treated as a dimensionless index that increases as the relative variance of the signal’s amplitude grows, reflecting a system’s increased sensitivity to fluctuations rather than to the mean level alone.

In informal models, amplitudmis is described qualitatively as a function that rises with the coefficient of variation of the amplitude. It is not equivalent to, nor a replacement for, measures such as signal-to-noise ratio or modulation depth, but it is discussed as a complementary way to capture how amplitude fluctuations might affect performance in detection, processing, or perception.

Applications of the idea occur mainly in thought experiments, simulations, or discussions about robustness of detectors under amplitude noise. Its use is theoretical and there is little to no empirical validation in mainstream research, with varying proposals for how to define and compute it.

Status and criticism: amplitudmis has no broad consensus and is considered speculative. Because definitions and formulas can differ across authors, readers should treat it as a hypothetical construct rather than established terminology.
