摘　　要：工程实践中往往会应用到多种信号形式的信号源。为了实现信号源中信号的多样性,采用直接数字频率合成技术设计了一种任意波形发生器。波形存储器中存储的波形数据是任意波形发生器的关键,详细说明了使用Matlab生成波形存储器中波形数据的方法。采用上述方法得到了一种工程实践中常用的扫频信号仿真波形图。实验表明,所设计的任意波形发生器实现简单,可编程,适合广泛应用于工程实践中。The signal sources in the various forms are often applied to engineering practice. In order to realize the signal diversity of signal sources, an arbitrary waveform generator was designed with the direct digital frequency synthesis technolo- gy. The waveform data stored in waveform memory is the key of the arbitrary waveform generator. A method to generate the waveform data in waveform memory by Matlab is described in detail. A swept frequency signal simulation oscillogram usually used in engineering practice was obtined by the above method. The arbitrary waveform generator designed with this method is easy to realize, programmable and suitable for engineering application.
