.Modelica.Clocked.RealSignals.Sampler.SuperSample

Information

This block super-samples the clocked Real input signal u and provides it as clocked output signal y.

To be more precise: The clock of y is factor-times faster than the clock of u. At every tick of the clock of y, the value of y is set to the value of u from the last tick of the clock of u. The first activation of the clock of y coincides with the first activation of the clock of u. By default, the super-sampling factor is inferred, that is, it must be defined somewhere else. If parameter inferFactor = false, then the super-sampling factor is defined by Integer parameter factor.

For control applications this block introduces unnecessary "vibrations". In such a case it is better to use block SuperSampleInterpolated instead.

Example

The following example samples a sine signal with a periodic clock of 20 ms period, and then super-samples the resulting clocked signal with a factor of 3:

	model	simulation result

As can be seen, superSample introduces factor-1 additional clock ticks for the output y. The super-sampling factor = 3 is displayed in the icon of the superSample block. Note the up-arrow in the icon of the superSample block indicates that the clock of superSample.y is faster as the clock of superSample.u.
