摘要
无限脉冲响应(IIR)数字滤波器在很多领域中有着广阔的应用。本文用Butterworth法、切比雪夫1法法、切比雪夫2法通过MATLAB仿真软件对几种给定性能的IIR数字滤波器进行了仿真设计,并用基于MOTOROLA公司的M68HC11单片机进行了硬件设计实现,表明数字滤波器具有灵活、方便、功能强的特点。
The Infinite Impulse Response (IIR) Digital filter has many applications in a lot of realms. This paper goes on emulation design to several IIR digital wave filters of given performance .It uses the MATLAB emulation software in Butterworth method, Chebyshev 1 law and Chebyshev 2 law. It also implement the hardware design based on M68HC11 one-chip computer of MOTOROLA Company. The rusults indicate that the digital filter is flexible, convenient, and has strong function.
