Coherent phase-locked synchronous oscillator

A coherent phase-locked synchronous oscillator (CPSO) is a coherent synchronisation and tracking network developed using a synchronous oscillator and a feedback network, external to the synchronous oscillator (SO). It is a unique network whose noise bandwidth is fully independent of its tracking range and has absolute coherency throughout the tracking range. It has several orders of magnitude wider tracking range for a given input signal/noise ratio than any other tracking network.
