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.

Parameters (4)

wMin	Value: Type: Real Description: Start frequency
wMax	Value: Type: Real Description: End frequency
startTime	Value: 0 Type: Time (s) Description: Start time of frequency sweep
duration	Value: Type: Time (s) Description: Duration of ramp (= 0.0 gives a Step)

Connectors (1)
