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:
“I had let preadolescence creep up on me without paying much attentionand I seriously underestimated this insidious phase of child development. You hear about it, but youre not a true believer until it jumps out at you in the shape of your own, until recently quite companionable child.”
—Susan Ferraro (20th century)
“Your next-door neighbour ... is not a man; he is an environment. He is the barking of a dog; he is the noise of a pianola; he is a dispute about a party wall; he is drains that are worse than yours, or roses that are better than yours.”
—Gilbert Keith Chesterton (18741936)
