quadrature filter meaning in Chinese

正交滤波器

The wavelet filters adopted in the progress are the conjugate quadrature filter bank ( cqf ) and the daubechies ( daub ) based filter . analysis and comparison of the results are made when different wavelet filters work
同时对不同频段信号的分离采用不同的小波滤波器? ?共轭正交滤波器( cqf )与daubechies ( daub )小波滤波器的滤波效果进行了比较和分析。
In addition , according to the characteristics of wavelet packet transform and that of conjugate quadrature filter bank , we bring forward the ameliorated arithmetic of wavelet packet . the amplitude of time - varying harmonics can be measured accurately through the ameliorated arithmetic
另外我们结合小波包分解和正交镜像对称滤波器的特点，提出了小波包的改进算法，利用该算法可对时变谐波信号的幅值进行比较精确的分析。
