Excerpt from Characterization of Frequency Stability This paper attempts to present (as concisely as practical) adequate, self-consistent definitions of frequency stability. Since more than one definition of frequency stability is presented, an important part of this paper (perhaps the most important part) deals with translations among the suggested definitions of frequency stability. The applicability of these definitions to the more common noise models is demonstrated. Consistent with an attempt to be concise, the references cited have been selected on the basis of being of most value to the reader rather than on the basis of being exhaustive. An exhaustive reference list covering the subject of frequency stability would itself be a voluminous publication.
