摘　　要：现行国内数字存储示波器(DSO)的数学功能仅完成通道间的加减乘除运算,为了让用户看到经过微积分器件之后的原始波形,必须对DSO的数学功能进行拓展。基于数值微分和数值积分的基本原理,设计了其在DSO中的应用,并给出了波形原始数据经过此种运算后的效果图,实验结果证明数值微积分运用于DSO中完善了其数据分析的处理能力。Existing domestic digital storage oscilloscope（DSO）only completed the mathematical functions of addition and subtraction multiplication and division between the channels,to allow users to see through the calculus of the original waveform after the device,must develop a mathematical function on the DSO.Based on the basic principles of the numerical differentiation and numerical integration,designed an application with them in DSO,and gave the original waveform＇ data after the effects of such operations plans,and the experimental results showed that numerical integration and numerical differentiation applied to the DSO can improve its power of data processing.
