数字信号发生器，可以产生各种常用波形，如三角函数，正弦函数，白噪声等。是基于matlab的虚拟仪器。-Digital signal generator, can produce a variety of commonly used waveforms, such as trigonometric functions, the sine function, white noise or the like. Virtual instrument based on matlab.

在labview虚拟仪器中，利用波形生成和波形测量选板，使用选板的函数节点，设计显示多种波形信号发生器，同时测量信号的幅值和电平。-In labview virtual instrument, using waveform generation and waveform measurements palette using palette function node design shows a variety of waveform signal generator, simultaneous
