Description

This block is an event generator of a phase noisy oscillator.
For each generated events, the phase (that must be in -2*Pi,2*Pi) is read on the regular input port.
The event dates are computed by the help of the following continuous threshold :

$$\begin{eqnarray} t - (kT_{0} + \delta \tilde{\phi}(t)\frac{T_{0}}{2\pi}) = 0 \end{eqnarray}$$

with To the period of the oscillator, and $\delta \tilde{\phi}(t)$ the phase noise of the oscillator.

Dialog box
