摘要
基于紧支撑正交小波变换理论和多分辨率分析特性的应用研究，提出了信号的数字滤波的算法方案，并通过仿真对算法进行了验证和比较。仿真结果表明，小波分析法在数字滤波中的有效性和优越性。
Based on application study of close support cross wavelet transform theory and its multi-resolution analysis characteristic, the digital filtering arithmetic for signal is put forward. The arithmetic is validated and analyzed by simulation. The simulation and analysis results prove the validity and adoantage of wave let analysis in digital filtering.
