| 摘 要： | 在降低采样速率时，可使用简单的内插方案提供高阶Ｄ／Ａ转换，来提高再现信号的准确度，通过仿真对各阶转换误差公式的检验结果表明：应用三阶Ｄ／Ａ转换获得与以二倍采样的零阶转换同样准确的再现数据。

| Abstract: | When the sample rate is decreased,the high order digital analog (D/A) conversion can be provided by using simple interpolation scheme,so that the accuracy of the reconstructed signal is raised.The validity of each order error equations were checked using simulation.Results indicated that use of third order D/A conversion yieled as accurate a reproduction of data as zero order conversion at twice the sampling rate. |
