.Modelica.Blocks.Math.ContinuousMean

Information

This block continuously calculates the mean value of its input signal. It uses the function:

     integral( u over time)
y = ------------------------
        time - startTime

This can be used to determine the empirical expectation value of a random signal, such as generated by the Noise blocks.

The parameter t_eps is used to avoid large fluctuations but can be set to zero (the mean value computation starts at <simulation start time> but is only returned after an additional t_eps and before that time instant y = u).

See also the Mean block for a sampled implementation.

This block is demonstrated in the examples UniformNoiseProperties and NormalNoiseProperties.
