Information

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

The output y performs a logarithmic frequency sweep. The logarithm of frequency w performs a linear ramp from log10(wMin) to log10(wMax). The output is the decimal power of this logarithmic ramp.

For time < startTime the output is equal to wMin.

For time > startTime+duration the output is equal to wMax.
