摘要:
提出了一种变采样率滤波的优化算法,根据该算法设计了一种利用多通道数字滤波来进行离散小波变换(DWT)的硬件电路,并最终在大规模的CPLD器件中得到了实现.与传统的软件计算方法不同,该硬件能够根据需要实时计算被测信号的 离散小波变换.实验结果表明,本文的方法效果良好.
Abstract:
A optimized algorithm of multirate filter is proposed. Base on it, we design a multi-channel filter circuit which can perform discrete wavelet transform and implement it in large scale CPLD device. Unlike software computing method,this hardware can perform DWT in realtime according to our need.The experiment indicates that this method is efficient.
