pyeeg.simulate.Phasor

class pyeeg.simulate.Phasor(frequency=10.0, dt=0.001, seed=42)

One-dimensional phase oscillator with sinusoidal readout.

The phase \(\phi\) evolves according to \(\dot{\phi} = \omega + I\) where \(\omega = 2 \pi f\), and the readout is \(\sin(\phi)\).

Parameters:

• frequency (float) – The oscillation frequency in Hz. Must be non-negative.

• dt (float) – The integration time step in seconds.

• seed (int) – The random seed used to initialise the node’s random number generator.

Raises:

ValueError – If frequency is negative.

Methods

Phasor.read_out()	Return the scalar readout of the oscillator.
Phasor.simulate([x0, tmax, noise, I])	Simulate the oscillator and return its phase and readout.
Phasor.step([I, noise])	Advance the phase by one integration step (Euler method).
