摘　　要：提出了一种设计高效窄过渡带宽FIR滤波器的新方法。该方法以传统的频率响应屏蔽(FRM)方法为基础,通过选择特定的原型滤波器来降低合成的数字FIR滤波器的复杂度。本文研究了该方法的原理、实现结构和设计方法,并通过设计实例证明了此方法的有效性。A new approach to the design of efficient sharp finite impulse response (FIR) filters is presented. Based on traditional rrequency-response-masking technique, this method reduced the complexity of the synthesized FIR filter through choosing special base filters. In this paper, the principle, implementation structure and design method are presented and its efficiency is proved with design examples.
