| 摘 要： | 文章主要介绍了DAC器件在幅频特性上存在的Sinc函数衰落特性，分析了该现象产生的机理。针对性地提出了三种解决办法：采用数字内插技术提高转换速率方法、采用数字滤波器进行预失真处理方法、采用模拟滤波器进行后补偿处理方法。并对其分别进行了详细分析，给出了补偿后的效果。

| Abstract: | This paper describes the rolls off according to the Sinc frequency response envelope of DAC, and analyses the reason. Three equalizing techniques are given： increase the update rate by interpolation, using digital filter to pre-equalizing and using analog filter to post-equalizing. AT the same time, the results of them are also given in the paper. |
