Realization of Filter Bank Based on FPGA
The principle of filter bank is introduced briefly, then the realization methods based on FPGA are presented in detailed. By parallel-to-serial conversion, realization structures of FIR and FFT which can save multiplier resource are proposed. The realization structure of rounding towards nearest integer is also put forward. These measures guarantee the realizability of filter bank in single FPGA chip.
