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:

    The problem of the twentieth century is the problem of the color-line—the relation of the darker to the lighter races of men in Asia and Africa, in America and the islands of the sea. It was a phase of this problem that caused the Civil War.
    —W.E.B. (William Edward Burghardt)

    Speak, ye that ride on white asses, ye that sit in judgment, and walk by the way.
    They that are delivered from the noise of archers in the places of
    drawing water, there shall they rehearse the righteous acts of the
    Lord,
    Bible: Hebrew Judges (l. V, 10–11)
