Abstract	In this paper, a simple method is presented to design two-channel hybrid filter banks satisfying near-perfect reconstruction. The analog analysis filters to divide the overall system bandwidth are not the low-pass, band-pass or high-pass filters by using conventional methods, but analog filters that satisfy the perfect reconstruction property. The digital synthesis filters are designed by means of the optimization method based on IFFT to ensure the near-perfect reconstruction. A two-channel hybrid filter bank with 2 taps analysis filters and 64 taps synthesis filters, which introduces $0.2times10^{-3}$ dB average deviation from 0 dB distortion and -100 dB average aliasing, are suitable for systems up to 12 bit resolution and the HFB has $0.3times10^{-3}$ dB max deviation from 0 dB distortion and -90 dB max aliasing
