正交镜像滤波器的设计，从正交镜像滤波器的远离出发设计,而且从结果中观察其相位和幅度。- Design a two-channel QMF filter bank
The four filters in the filter bank are based on a lowpass prototype H(z)
which is designed by this procedure. The analysis filters are HL(z) and
HH(z) and the synthesis filters are GL(z) and GH(z),
HL(z) = H(z) HH(z) = H(-z)
GL(z) = 2 H(z) GH(z) =-2 H(-z
