ABSTRACT:
A system and method of estimating random and periodic phase noise components based on measurement of phase jitter in a given signal uses a difference filter to attenuate low frequency random noise components and a process of obtaining timing measurements at a plurality of sampling frequencies in order to de-alias identified noise spurs. Such technology is especially well-suited for devices capable of undersampling a jitter signal, such as continuous time interval analyzers (CTIAs).
