RMS frequency error of injection-synchronized oscillators

This correspondence presents a simple explanation on the operation and equation of phase motion of an injectionsynchronized oscillator in the presence of incoming noise in a simple way with particular reference to the effect of partly instantaneous limiting, due to the self-bias circuit of the oscillator. A simple relation between the mean-square frequency error and the time constant of the self-bias circuit has also been found by the application of the Fokker-Planck technique.
