The application of virtual simulation experiment platform has changed the traditional teaching method fundamentally, reduce the cost of laboratory construction and management, which has important reference value to realize the remote experiment teaching. Through this experiment, students' interest in knowledge is cultivated and innovation ability is enhanced. The virtual simulation experiment platform consists of hardware and software function modules, which are both designed in this thesis.There are five experiments available for choose as following: virtual oscillograph, spectrum analysis, formula-wave generator, temperature measurement with K-thermocouple, Fourier transform comparison.
