Abstract :
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
