Abstract: The virtual simulation technology is used to the experimental teaching of Electronic design courses and multifunctional active filter experiment system that based on the Analog Discovery.It is designed starting from the idea of improve the traditional experimental teaching mode.A set of complete circuit design and development process is included in this system.Students design and simulate a cir cuit with Multisim circuit firstly,then use the Analog Discovery suite to buildi a multifunctional active filter circuit,finally the real-time dynamic display of the filtered signal is realized via Waveforms software.Then complete the entire multi-active filter design experiments.The practice shows that based on Analog Discovery and Multisim simulation software,Waveforms graphical software,the system can effectively complete the design and development of multi-function active filter.It is agile and convenient with a strong maneuverability and clear results,which make up for the deficiency existing in the traditional experiment.
