三维非分离型有限长冲击响应滤波器组的设计

A NEW DESIGN OF 3-D NONSEPARABLE FIR FILTERS

提出了一种新的三维非分离线性相位二通道并具有完全重构的有限长冲击响应滤波器组的设计方法，与McClellan变换采用频率变换不同的是该方法是利用变量代换方法。通过调整一维窗函数的参数和传递函数可以灵活地控制三维滤波器的频率特性。最后给出了几个设计实例。

This paper presents a new technique to edsign 3-D two-channel filters FIR, linere phase and perfect reconstruction.This design technique is based on the transformation of variable methods which is different from frequency transformation of McClellan's. The frequency characteristics are adjusted by changing the 1-D window function and transformation function. Several examples are designed and shown in the end.
