Abstract：

This paper introduces a design and implementation of a virtual oscilloscope based on sound card. The oscilloscope can process the input signal of sound card through software to realize waveform display, measurement and analysis. Firstly, the basic principle and usage of sound card are introduced, and then the software design and algorithm implementation of virtual oscilloscope are introduced. Finally, the performance and reliability of the oscilloscope are verified through experiments.

Keywords: sound card, virtual oscilloscope, software design, algorithm implementation, performance test
