Abstract : Hybrid filter banks (HFB) Analog/Digital (A/D) systems permit wide-band, high frequency conversion. This paper presents theoretical results on the equivalence between analog and digital analysis filter banks with A/D Converters (ADC) for bandlimited signals. We give the performance of HFB ADCs associated with easy-to-implement analog filters and synthesis bank obtained by truncating the impulse responses of ideal filters permitting perfect reconstruction, in both cases of discontinuous and continuous frequency responses.
