1. Time-domain noise characterization

1.1 Ideal oscillator and real oscillator

The signal delivered by an ideal oscillator of nominal frequency ν ₀ can be modeled by the following relationship:

V (t) = V_{0} \sin (2 π ν_{0} t)

^( 1 )

However, a real oscillator is subject to disturbances, either deterministic or random, which affect its amplitude and phase (figure...
