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

Enrico Rubiola, Jacques Millo, Nora Meyne, Joseph Achkar, Filippo Levi, Archita Hati

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.
