【摘要】 本文介绍了数字滤波器的设计,着重阐述了怎样用单板机和微机实现数字滤波器。内容分两部分,一、用TP-801单板机实现IIR滤波器,并分析了滤波结果,二、用窗口法和频率采样法设计FIR滤波器,给出了FIR数字滤波器的冲激响应h(n)。更多还原

【Abstract】 In this paper, we intruduced the design and realization of digital filters, and focased on the realization of digital filter by using single board computer and micro - computer. In the first part of the paper the realization of IIR Filter byTF801 computer and the filtered result were discassed. In the second part the FIR Filter was disigned using method of windowing and frepuency sampling method. A impulse response h(n) of FIR digital filers was presented as well.更多还原
