StateSpace Discrete-time State Space block
	TransferFunction Discrete-time Transfer Function block
	PI Discrete-time PI controller
	MovingAverage Moving average filter (= FIR filter with coefficients a = fill(1/n,n), but implemented recursively)
	FIRbyCoefficients FIR filter defined by coefficients

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

This package contains blocks that are designed for periodically clocked system. Changing the sample rate (without changing at the same time the parameters of the block), or using the blocks on non-periodically clocked signals, will usually result in non-expected behavior.
