本文叙述的数字/交流(D/转换线路,是根据本室的模拟项目需要研制而成,该转换线路所用元件较少,工作稳定性好,实现起来较为方便,应用范围不仅适于数字/交流,也可使用于数字/直流转换的场合。本文线路具有转换精度较高,失真度小(包括曲线的平滑度和相位误差等)的特点。转换的频带较宽,转换的硬件和软件都较为简单,操作使用灵活方便。以上特点是软件实现的数字/交流转换所不及的。
Described in this article digital / communication (D / conversion lines, is based on the project needs to be developed from the studio project, the conversion lines less components used, good job stability, to achieve more convenient, not only for the application of digital / AC, can also be used in digital / DC conversion of the occasion.The line has high conversion accuracy, low distortion (including curve smoothness and phase error, etc.) conversion bandwidth is wide, the conversion of hardware and software are Relatively simple, flexible and convenient operation and use.The above features are not achieved by digital / AC conversion software.
