摘要:
以线阵CCD图象传感器TCD1209D在纺织卷印自动纠偏中对线信号的采样为例,在分析对比基础上归纳出IIR数字滤波器特点:用较低的阶数获得很高的频率选择性、占用存储单元少经济性好、滤波效率高、在相同门级规模和相同时钟频率下可以提供更好的带外衰减特性.针对TCD1209D输出信号所受干扰,提出了应用巴特沃滤波器的方案,对滤波器的系数和阶数进行了计算.针对IIR滤波器的相移特性,采用了正向滤波、反向滤波、最后加权平均的算法,实现了零相位数字滤波.给出了由DSP集成电路TMS320F2407实现的方案和部分参考程序.
Abstract:
With the linear CCD image sensor TCD1209D output signal processing as an example, on the basis of analyzing and comparing the author summed up IIR digital filters’ characteristics: with a lower order to achieve high frequency selectivity, taking up less storage modules, high filter efficiency, at the same door scale and the same clock frequency IIR digital filter can provide better outsideband attenuation characteristics. For the type of disturbs, the author provides apply the method of choosing the Butterworth filter, and the filter coefficients and order are calculated. Against IIR filter phase shift, adopt filtering, reverse filtering and finally weighted average algorithm to achieve the zerophase digital filtering are proposed. The article also provides the hardware solutions by using the DSP IC TMS320F2407 and the major part of reference codes.
