摘　　要：基于NI ELVIS Ⅱ系统和LabVIEW开发平台,设计了分层次的滤波器实验.在基础训练层次,利用NI ELVIS Ⅱ系统内部集成的相关仪器进行一阶高通滤波器电路参量测量、激励信号输入以及响应信号检测,并通过LabVIEW数据处理例程,实现截止频率、幅频特性参量的计算和幅频特性曲线的绘制.Filter experiments in various levels were designed based on NI ELVIS II system and LabVIEW platform. In the grounding level, circuit parametric measurement about a first order high- pass filter, excitation signal input and response signal detection were performed using the relevant in- struments integrated within the NI ELVIS II system. The cut-off frequency and the amplitude-fre- quency characteristic parameters were calculated and the curve of amplitude-frequency was draw using LabVIEW data processing routine.
