中文摘要：
为了对DSO存储波形进行进一步的分析和处理，利用LabVIEW在工程应用和信号处理上的优势，编写了具有DSO存储波形显示、频谱分析、滤波处理、单频信息分析的多功能软件。结合实例对滤波处理和提取单频信息方法的处理结果进行了对比分析，根据两种方法的原理和优缺点，指出了各自的应用条件，可为工程中DSO存储波形的分析和处理提供指导。
英文摘要：
To analyze and process waveform stored in DSO, a muhifunctional software is developed with the functions of stored waveform display, spectrum analysis, filtering processing and single frequency information analysis by making use of ad- vantages of LabVIEW in engineering application and signal processing. Combined with examples, the processing result based on filtering processing is compared with one based on single frequency information extraction method. On the basis of comparing their principles, advantages and disadvantages, their respective application condition is given, which provide reference for analysis and processing of waveform stored in DSO.
