摘要
通过分析二维ＦＩＲ数字滤波器设计的特点，提出一种频域—空域交替逼近的ＣＡＤ方法，并给出了应用此方法的设计示例．结果表明，这种方法简捷实用。
Based on analysing the design characteristics of 2D FIR digital filters, this paper presents a 2D FIR digital filters CAD method by frequencyspatial domains alternate approaching, and give two applied examples. The results show that this CAD method is suitable particularly for designing 2D FIR digital filters with specical frequency characteristics.
