Digital compensation for uneven frequency response of analog filters from the hybrid filter bank
This article describes a method to compensate distortions carried by analog analysis filters of a hybrid filter bank. Were obtained expressions describing hybrid filter bank based ADC with addition of compensator. Described processing system was modeled and quantitative measurements of signal distortions were calculated for system with and without compensator. Were shown that insertion of a compensator can significantly improve the characteristics of the system. Methods to increase the computational efficiency of the compensator were described. Dependencies were obtained between the accuracy of compensation and the computational complexity of the compensator.
