摘要
数字滤波器是语音、图象处理、模式识别以及谱分析中的基本运算的处理运算。DSP由于其本身具有并行的硬件乘法器、流水结构以及快速的片内存储器等资源,其技术已广泛地应用于噪声及振动的各个领域.本文研究DSP中有限冲击响应(FIR)滤波器的原理并结合基于TM320C5416开发的采集板,介绍FIR滤波器设计及DSP中FIR滤波器的实现方法。并给出了基于TM320C5416相应的实现程序.该原理已应用于网络化数据采集系统中,效果良好.
Digital filter is the basic arithmetic of speech, image processing, model recognition and spectrum analysis. And with many excellent features, DSP is used widely in various fields such as vibration and noisy filter recently, This paper presents a research on the principal of FIR digital filter which is used in digital signal processor （DSP）. The methods of designing FIR filter and implement FIR in DSP are also introduced combining with the sampling board we developed based on TMS320C5416.At last, the main program of DSP is given. This algorithm has been well used in data acquisitive system based on Ethernet.
