Beschreibung
Zusammenfassung:	The invention provides a high-precision simulation given circuit, belonging to the AC motor driver technical field. The invention comprises a differential simulation voltage input terminal, a differential receiving circuit, a simulation optical screen, an A/D converter circuit and a processor with a serial peripheral interface SPI. The differential simulation voltage input is connected with the differential receiving circuit which is connected with the simulation optical screen which is connected with A/D converter circuit which is connected with the processor with the SPI interface through the SPI interface. The invention has the advantages of implementing high-precision speed simulation giving and restraining the common mode interference signals on a transmission line.
