Application of Vernier Interpolation for Digital Time Error Measurement

Timing (synchronization) signals in telecommunication networks are affected by a variety of distortion processes, which lower their quality. One of such processes is long-term random phase variation (wander), characterized by a bandwidth below 10 Hz. The basic measure for estimating the quality of timing signal is time error TE, being the difference of phases of the investigated signal and the reference signal, expressed in time units. The precise measurement of TE is of key significance for appropriate estimation of the quality of the timing signal under test.
