I_sffm

Single-frequency FM current source

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

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.

Note:

  • 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.
