| Abstract: | Digital filter is the basic arithmetic of speech, image processing, model recognition and spectrum analysis. And with manyexcellent features, DSP is used widely in various fields such as vibration and noisy filter recently. This paper presents a research onthe principal of FIR digital filter which is used in digital signal processor (DSP). The methods of designing FIR filter and implemenFIR in DSP are also introduced combining with the sampling board we developed based on TMS320C5416.At last, the main programof DSP is given. This algorithm has been well used in data acquisitive system based on Ethernet. |
