Hardware-Efficient Implementation of Half-Band IIR Filter for Interpolation and Decimation

This brief deals with a simple heuristic method for the hardware optimization of a half-band infinite-impulse response (IIR) filter. The optimization method that is proposed here is intended for a quick design selection at the system level, without the need for computationally intensive calculations...
