信号发生与信号调理，LabView，可以产生信号；信号处理；频谱显示-Signal generation and signal conditioning, LabView, you can generate a signal signal processing spectrum display

运用数字FIR滤波器调理信号，因为FIR滤波器的相频相应是线性的，可以防止时域数据发生畸变，并有效的滤除干扰信号-Conditioned signal using digital FIR filter, the FIR filter as linear phase frequency corresponding possible to prevent the distortion of the time-domain data, and effectively filter interferen
