Jitter and Phasenoise Devices simulation

Jitter and Phasenoise Devices simulation. Jitter is a measurement of the variations in the time domain, and essentially describes how far the signal period has wandered from its ideal value. Typically, deviations below 10 MHz are not classified as jitter, but as wander or drift.
