摘要

摘要本文讨论了应用电工元件(电阻器、电容-模拟滤波器)和数字巴特沃斯滤波器(无限脉冲响应)求解一阶无源滤波器(低通和高通)的方法。介绍了滤波器的设计和实现过程,并对相同输入信号下的模拟滤波器和数字滤波器输出进行了比较。所设计的滤波器已经用于教育目的,旨在解释设计信号处理滤波器所需功能的技术。

Digital Implementation of Butterworth First–Order Filter Type IIR
Abstract The paper deals with the solution of the first–order passive filters (low–pass and high–pass) applying electrotechnical elements (resistor, capacitor - analogue filter) and digital Butterworth filter type IIR (Infinite Impulse Response). Procedure of the filters design and implementation is described, and the analogue and digital filter outputs with the same input signal are compared. The designed filters have already served for education purposes with the intention to bring an explanation of techniques for designing required functionality of the signal processing filters.
