WOLFRAM SYSTEM MODELER

SampleClocked

Sample the continuous-time, Real input signal and provide it as clocked output signal. The clock is provided as input signal

Wolfram Language

In[1]:=

SystemModel["Modelica_Synchronous.RealSignals.Sampler.SampleClocked"]

Out[1]:=

Information

This block is similar to the Sample block. The only difference is that a clock signal is provided via a second input and the output is associated to this clock.

Note, it does not make much sense to vectorize this block, because then also the clock input is vectorized. Instead, if the input signal is a vector, use block SampleVectorizedAndClocked that has a vector Real input and output, as well as a scalar clock input.

Example

The following example samples a sine signal with a periodic clock of 20 ms period:
