modelV_sffm
Single-frequency FM voltage source
Extends from Modelica.Electrical.Analog.Interfaces.OnePort (Component with two electrical pins p and n and current i from p to n).
Information
The single-frequency frequency modulation source generates a carrier signal of the frequency FC. This signal is modulated by the signal frequency FS. See the formula in the Modelica text.
Attention
- All parameters of sources should be set explicitly.
- since TSTEP and TSTOP are not available for modeling in Modelica, differences to SPICE may occur if not all parameters are set.
