直接型FIR滤波器的优化和实现

Optimization and Realization of Direct-type FIR Filter

在许多信息处理过程中,如对信号的过滤、检测、预测等,都要广泛地用到滤波器,数字滤波器是数字信号处理中使用最广泛的一种方法,实现方法主要有IIR滤波器和FIR滤波器两种。本文对直接型的FIR滤波器进行了优化和实现。

Filter is using in many information processing such as filtering, monitoring and expecting. Digital filter is the most popular way in digital signal processing. There are two main ways：IIR filter and FIR filter. Here, we optimize and carry out the FIR filter.
