| 摘 要： | 本文详细介绍了虚拟滤波器去除噪声的LabVIEW程序的设计和开发过程。在PC机LabVIEW软件中模拟产生一个接近于实际信号的带噪声的信号,生成一个带噪声的信号发生装置,选择滤波速度较快的无限冲激响应滤波器IIR,对于滤波后的信号以数组的方式得到,通过合理的显示方式,显示滤波前后的时域波形。

| Abstract: | The process of designing and developing a virtual filter for denoising on LabVIEW is particularly introduced in this paper. A virtual noised signal similar to the real one is generated in LabVIEW environment, and also a generator of noised signal is gener-ated. The IIR filter is selected. The signal filtered is denoted in the form of array, and its wave in time domain is displayed in logi-cal form. |
