Models an deal discrete resonator with delay considering op-amp saturation.

Library

Description

The Ideal Resonator block models a real discrete resonator with delay considering op-amp saturation.

The implemented transfer function in the z-domain is

The saturation levels of the operational amplifier are modeled using a saturation block inside the feedback loop of the resonator.

Parameters

  • Sample Time: Period of the sampling signal in s (Ts = 1/fs, where fs is the sampling frequency)
  • Saturation: Saturation voltage of the op-amp used in the integrator in V
