Phase effect in frequency measurements of a quartz crystal using the pulse coincidence principle

Measurement of time-frequency parameters is a task required in quite diverse applications, which include clock synchronization, radar systems, sensors, etc. This is the reason why frequency measurement is one of the key processes in many systems. Accordingly, approximation of a signal frequency has been actively researched and plenty of measurement techniques have been proposed. In the last years, the principle of rational approximations has been evaluated for frequency measuring, particularly for sensors. In this work, we examine the effect of phase in input signals during measurement, when the principle of rational approximations is applied. Data from an experimental measurement system is analyzed and conclusions are drawn.
