摘要

本文描述了窄带FIR线性相位低通数字微分器的非迭代设计的一个简单公式。滤波器的频率响应在直流附近是平坦的，并且在阻带中具有等间隔的零。设计问题的制定是为了避免同类滤波器设计标准方法在设计长脉冲响应窄带滤波器时的复杂性和不适应性。

Narrowband lowpass digital differentiator design

This paper describes a simple formulation for the non-iterative design of narrowband FIR linear-phase low-pass digital differentiators. The frequency response of the filters is flat around dc and have equally spaced nulls in the stopband. The design problem is formulated so as to avoid the complexity or ill conditioning of standard methods for the design of similar filters when those methods are used to design narrowband filters with long impulse responses.
