摘要
首先介绍了虚拟仪器,然后介绍了LabVIEW,接着介绍了基于LabVIEW去除噪声的设计过程。首先在计算机上的LabVIEW软件中模拟产生一个带噪声的信号,然后选择无限冲激响应滤波器,对加噪声信号进行处理。通过仿真,可以显示滤波前后的波形图,对比显示的波形图,可以看出滤波器的效果。
This paper introduces the virtual instrument technology and the LabVIEW software. Also,it introduces the design process of noise removal based on LabVIEW. Firstly,the LabVIEW software produces a noisy signal on the computer. Secondly,an infinite impulse response filter is selected to process the noise signal. Through the simulation,the waveform is displayed before and after filtering. By comparing the displayed waveform,the filtering effect can be got.
