摘　　要：随着科技的飞速发展,任意波形发生器(AWG)逐渐成为常用的信号激励源解决方案。针对存储深度对任意波形发生器性能的制约,从降低单个采样点存储空间的角度,提出了一种提高直接数字波形合成(DDWS)技术存储深度的新方法,该方法通过存储幅值量化数据相对增量(当前采样点相对于前一采样点幅值量化数据的增量)以压缩存储单个采样点的存储空间,从而提高存储深度。同时对其进行了仿真验证,仿真结果表明,在存储容量一定的条件下,提出的新方法能够有效地提高存储深度。With the high-speed development of science and technology,the arbitrary waveform generator(AWG)has become the preferred solution for simulation signals.A new method is proposed to increase the storage depth of direct digital waveform synthesis(DDWS)by reducing the memory size of single sampling point.The new method stores the relative increment of the amplitude quantization data to reduce the memory size of single sampling point and increase the storage depth.Numerical simulation has been done to verify the effectiveness of the proposed method.
