摘要

利用广义麦克莱伦变换，提出了一种具有中心对称频率响应的二维零相位有限脉冲响应(FIR)风扇滤波器的设计方法。这些公式是根据规定的风扇滤波器的频率响应规格推导出来的，在均方意义上是最优的。通过设计算例说明了该方法的有效性。

Design of centrally symmetric 2-D FIR fan filters using the McClellan transform

The authors present a novel design method for 2-D zero-phase finite impulse response (FIR) fan filters with centrally symmetric frequency responses, via the generalized McClellan transform. The formulas are derived from the prescribed frequency response specifications of the fan filter and are optimal in the mean square sense. The efficiency of the method is shown through design examples.<>
