Abstract : The analysis of the phase difference between an input signal, which consists of a desired signal and an undesired interfering signal, and a reference oscillator in a feedback system is discussed. The ordinary small angle linearization is adapted to solve the problem. The total mean square phase error is obtained as a function of the desired and undesired power ratio. With the aid of these results and a particular interference threshold, it is then possible to determine the amount of mean square or root mean square (rms) error due to interference and an acceptable limit of the signal-to-interference ratio that can be tolerated.
