脉冲测试系统最佳带宽的数值计算

Numerical Calculation of Optimum Bandwidth for a Pulse Measurement System

由于受测试系统带宽的限制，脉冲信号在测试过程中其能量将受到不同程度的损失。本文用Romberg数值积分法计算出在一定能量损耗限值要求下的脉冲信号频谱宽度，并用付氏级数对其进行了信号重构验证，据此得出了脉冲信号测试系统带宽的最佳值。

Owing to bandwidth limit of a measuring system, the pulse signal energy is always wasted, when it is measured. This paper presents the pulse signal spectrum bandwidth using Romberg numerical integration algorithm under a certain energy wastage required. A reconstruction signal is obtained by Fourier Series, and the optimum bandwidth of the measurement system is also presented.
