SystemModel["Modelica.Blocks.Sources.SineVariableFrequencyAndAmplitude"]
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This signal source provides a sinusoidal signal with variable frequency f
and variable amplitude
,
i.e. the phase angle of the sine wave is integrated from 2*π*f.
Note that the initial value of the phase angle phi
defines the initial phase shift,
and that the parameter startTime
is omitted since the voltage can be kept equal to offset with setting the input amplitude
to zero.
