What is Phase Noise & Who Cares?

\n", "\n", "I'll let [Wikipedia](http://en.wikipedia.org/wiki/Phase_noise) speak on the matter:
\n", "\"In signal processing, 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.\"
