虚拟信号采集分析器

1）：利用信号发生器产生不同信号（信号的相关参数可调）

2）：在信号上叠加白噪声。

3）：对上述信号进行采样（采样频率可调）

4）：在采样的过程中利用均值滤波（每三个点取均值）

5）显示采样后的波形，并对其进行频率分析。

6）：将采样后的波形与原波形做比较（在同一坐标系中显示-Virtual signal acquisition Analyzer 1): Using the signal generator to produce different signals (signals adjustable parameters) 2): white noise superimposed on the signal. 3): The above signal is sampled (sampling frequency adjustable) 4): Using the mean filter (averaging three points each) 5) during the sampling process after sampling the waveform display, and its frequency analysis. 6): After sampling the waveform is compared with the original waveform (shown in the same coordinate system
