Synthesis of hybrid filter banks for A/D conversion with implementation constraints -optimized frequency response approach -
Teodor Petrescu, J. Oksman · 2006
Hybrid filter banks (HFB) need simple analog structures. Therefore, standard resonators are considered for the analog analysis filters. They are seen as input data of the design process and are kept unmodified throughout the design procedure. Direct resolution of simplified perfect reconstruction conditions gives primary synthesis filters which can be further optimized in order to minimize the reconstruction error.
