摘要

本文介绍了具有无混叠子带的混合模拟/数字滤波器组。由于单个滤波器的阻带衰减，输出处的混叠很小，而不是由于抵消，这是最大抽取滤波器组的情况。因此，模拟滤波器元件的精度要求是宽松的。

Two-channel hybrid analog/digital filter banks with alias-free subbands

This paper introduces hybrid analog/digital filter banks with alias-free subbands. The aliasing at the output is small due to stopband attenuation of the individual filters and not due to cancellation, which is the case in maximally decimated filter banks. Thus, the accuracy requirements of the analog filter components are relaxed.
