Block Modelica.ComplexBlocks.Sources.ComplexExpression
The (time varying) Complex output signal of this block can be defined in its parameter menu via variable y. The purpose is to support the easy definition of Complex expressions in a block diagram. Note, that "time" is a built-in variable that is always accessible and represents the "model time" and that Variable y is both a variable and a connector.

Block Modelica.ComplexBlocks.Sources.LogFrequencySweep
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.
