For this kind of course, experimental teaching is extremely significant. LabVIEW is a Graphics Language , aiming at control and signal processing, with the feature of visual, easy understanding and strong data processing，it also can support many kinds of hardware platform ,and has applied in many schools at home and abroad. it has very important real sense to design a experimental teaching system based on the LabVIEW aiming at enhancing students understanding of the basic theory courses and improving engineering capabilities. The?thesis?firstly?introduces?the?feature?of? LabVIEW,?and?experiments?on?LabVIEW??including?signal?analysis,?signal?sampling,?LTI?system?features,?system?simulation,?and?the?resonant?circuit.?Compared?with?the?traditional?experimental?teaching?system,?the?easy-understanding?graphical?programming?in?LabVIEW?and?its?powerful?I/O?drive?capability??not?only??increases?students?interest?in?the?experiment,?but?also?enhances?the?engineering?ability?of?students?to?combine?the?software?and?hardware.?The?experimental?system?constituted?by?these?modules?can?be?used?to?the?experimental?teaching?involved?in?the?signal?and?system?for?the?students?of?the?Electronics?specialty.
