Phase Noise

Phase noise is the frequency domain representation of rapid, short-term, random fluctuations in the phase of a waveform, caused by time domain instabilities ("jitter"). Generally speaking, radio frequency engineers speak of the phase noise of an oscillator, whereas digital system engineers work with the jitter of a clock.

Famous quotes containing the words phase and/or noise:

    It no longer makes sense to speak of “feeding problems” or “sleep problems” or “negative behavior” is if they were distinct categories, but to speak of “problems of development” and to search for the meaning of feeding and sleep disturbances or behavior disorders in the developmental phase which has produced them.
    Selma H. Fraiberg (20th century)

    Sweet bird, that shunn’st the noise of folly,
    Most musical, most melancholy!
    John Milton (1608–1674)
