有限状态机实现数字滤波问题的研究

A Study of Realizing Digital Filtering with Finite State Machine

用有限状态机实现数字滤波是数字滤波器设计的一种新方法,它消除了其他设计方法中普遍存在的有限字长效应问题,因而具有很好的稳定性。本文研究了用有限状态机实现数字滤波系统中的系统稳定性、系统的表达、硬件实现以及软件设计等问题。

The finite state machine realization of digital filtering is a new method to design digital filter. This method eliminates the effects of finite wordlength that exist in other methods. The stability of system is highly improved. In this psper, the problems of stability, representation, hardware realization and software design of digital filtering system realized by finite state machine are studied.
