Frequency Jump Detection and Analysis

Abstract

The detection of jumps in a frequency record is a challenging problem by either visual or mathematical means. The former takes considerable experience and judgment, and is therefore quite subjective, but has the advantage of providing insight into device behavior. The latter is more impartial and consistent, and can be automated. In combination, mathematical jump detection can be applied for automatic clock testing and monitoring. If a jump is detected, the record can then be inspected visually before deciding on the action required. This paper describes frequency jump detection algorithms that are included in a program for frequency stability analysis.
