Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
The simple converter circuit converts an analog sine signal into a N-bit (by default a 4 bit) logic signal, which is converted backward into an analog signal.
- Simulate for 0.2 s.
Compare the input voltage (aD_Converter.p.v) with the output voltage (dA_Converter.p.v). By changing N the influence of the digital signal width can be studied. Otherwise the trigger frequency pulse.period can be changed to see its influence.
