Vocabulary, Physical Quantities and Units for the Measurement of Amplitude Noise and Phase Noise

TL;DR

This paper advocates for the standardization of physical quantities, units, and terminology in amplitude and phase noise measurement to reduce confusion and promote international consistency.

Contribution

It clarifies physical quantities and promotes the adoption of SI units and unambiguous terminology in the field of noise measurement.

Findings

Highlights issues caused by non-SI units and terminology

Proposes standardized definitions and units for clarity

Encourages international consensus on measurement practices

Abstract

The widespread use of non-SI quantities and units, together with improper and misleading terminology, generates confusion in the domain of phase and amplitude noise. We discuss such physical quantities, units and terms with the purpose of stimulating a discussion between labs, and to agree for the full adoption of the International System of Units (SI) and clear, unambiguous terminology.
