文中设计了基于Labview的频谱分析仪，采用频谱分析原理。经过采样，使连续时间信号变为离散时间信号，然后利用Labview的强大的数字信号处理的功能，采样得到的数据进行滤波、加窗、FFT运算处理，得到信号的幅度谱、相位谱以及功率谱。并具有数字显示、图形绘制，数据储存等功能，实现了幅度谱和相位谱的分析。

In this paper, we design the spectrum analyzer based on Labview, which adopts the theory of spectrum analysis. After sampling, the continuous-time signal converts to a discrete-time signal, then use the powerful functions of Labview to process the digital signal. Sample filter, add windows and operate FFT processing to the data obtained, then we get the amplitude spectrum, the phase spectrum and the power spectrum of the signal. Also with the digital display, graphics, data storage and other functions, succeeding to analyse the amplitude spectrum and the phase spectrum of the superposition signal.
