| Abstract: | According to the design principle of virtual instrument,a kind of virtual simulation instrument that surveys the network frequency characteristic with LabVIEW is designed.This virtual instrument has the functions of random waveform generator and digital storage oscilloscope.Driving signals of different frequencies can be produced by adjusting different parameters,and the amplitude-frequency characteristic and phase characteristic of the network can be displayed fleetly. |
