1. Time-domain noise characterization
1.1 Ideal oscillator and real oscillator
The signal delivered by an ideal oscillator of nominal frequency ν0 can be modeled by the following relationship:
However, a real oscillator is subject to disturbances, either deterministic or random, which affect its amplitude and phase (figure 1). The signal it delivers...
