提出了一种全新的两通道混合滤波器组的设计方法，利用基于功率互补对的模拟分解滤波器，均匀分割输入模拟信号。利用IFFT实现了数字综合滤波器的设计，以保证近似完全重构，并提出了单路滤波的两通道混合滤波器组。32阶数字综合滤波器配合3阶模拟分解滤波器，具有2．2×10^-6dB的最大失真误差和-110dB的最大混叠误差，满足16bit的ADC系统要求。

英文摘要：

A new method is presented to design two-channel hybrid filter banks （HFB）. The analog analysis filters used to divide the overall system bandwidth are analog filters that satisfy the pairwise power complementary property. Using IFFT,the digital synthesis filters are designed to ensure the near perfect reconstruction. And the single filtered 2 channel HFB are presented. The two-channel hybrid filter banks with 3rd-order analysis filters and 32nd order FIR synthesis filters,which introduces 2.2 × 10^-6dB max deviation from 0dB distortion and 110dB max aliasing,are suitable for systems up to approximately 16 bits resolution.
