Abstract
A circuit for the asynchronous measurement of the phase jitter of an incoming signal, at least a part of which is digital, includes a differentiator for sensing pulse transitions of the incoming signal and a periodic function generator resetable by the differentiated pulses. Function valves generated by the function generator coincident with the differentiated pulses are added together and averaged to form an average value of phase jitter based on the number of incoming signal transitions that are sensed.
