Design of Virtual Oscilloscope Based on Sound Card

With the continuous advancement of modern science and information technology,oscilloscopes,as an electronic measurement and processing instrument,are also evolving and have become more and more sophisticated and smarter.Traditional analog oscilloscopes are affected by many factors such as low-frequency response capability and bandwidth limitation,and have become inadequate in many fields.The emergence of virtual oscilloscopes has solved these problems.This article uses LabVIEW18 version as the development platform to design and manufacture a virtual oscilloscope based on sound card.This article focuses on the functions and specific implementation of each module of the virtual oscilloscope,including data acquisition,user interface processing,waveform display,data analysis,and data output printing modules,and the system performance analysis is also carried out at the end.By analyzing the oscilloscope not only has a clear interface,simple operation,and complete functions,but also can accurately achieve waveform measurement and obtain correct results,which greatly improves the efficiency of the experiment.
