摘要
介绍一种基于ＭｃＣｌｅｌａｎ变换的二维ＦＩＲ滤波器设计方法，该方法首先选用滚余弦函数作为过渡带函数设计一维ＦＩＲ数字滤波器，然后应用ＭｃＣｌｅｌａｎ变换方法设计二维ＦＩＲ数字滤波器。这种设计可消除Ｇｉｂｂ＇ｓ现象。
How the two dimensional zero phase FIR filter is designed with McClellan transformation is introduced. Firstly, we use the cosin function as transition band function to get the one dimensional linear phase FIR. Then we use McClellan transformation to get the two dimensional zero phase FIR filter. It eliminates the Gibbes phenomenon and reduces the arthmetic level of the two dimensional FIR digital filter.
