在许多领域中，常常需要通过数模转换产生满足各种特殊要求的模拟信号，然而它需要必须提供相应信号的数据序列。为了无须提供相应信号的数据序列且能快速地获取各种特殊信号的数据序列，提出一种全新的从软件画的、扫描仪扫的或数码相机照的波形图中提取相应信号数据序列的方法。实验表明，利用该方法可方便地从波形图中提取出满足采样点数、幅度和数据位数等要求的波形数据序列，并通过数模转换等后可获得与原波形图一摸一样的波形信号。

Simulated special signal, produced by digital to analog converter, is needed in many fields, and the data sequences for producing relative signal must be gained. For quickly and easily getting signal data sequences (SDS), the method, which may be used to generate (SDS) from special waveform picture obtained by drawing software, scanner or digital camera, are presented. By experiments, SDS, which meet the given conditions including samples, amplitude and resolution, can be gained conveniently from waveform image, and through analog- to- digital conversion, etc , signal, whose waveform is as same as that in the original image, can be gained. The results show that the method can be used to extract the corresponding signal data sequence from waveform picture.
