Description

allan_overlap.m calculates the overlapping Allan deviation (ADEV) of a time domain signal. It is intended for stability analysis of frequency data, although the analysis can be applied to other types of data. Fractional frequency or phase data sets with sample rate or time stamp information are handled.
