Abstract :
A hybrid filter bank requiring only lowpass analog filters is described. This architecture is suitable for A/D and D/A conversion of wideband signals. The structure uses identical pairs of lowpass filter and mixer in each to achieve the perfect reconstruction of the continuous input signal.
