Multiplier-free band-selectable digital filters
Arnaud Santraine, S. Leprince, Fred J. Taylor · 2004
DSP applications, such as digital filters, are often multiply-accumulate (MAC) intensive. Furthermore, many applications require deeply embedded low-power, high-speed solutions. Their physical implementation continues to be a challenge. A MAC-free bandpass and bandstop digital filter design paradigm is presented that can meet demanding performance and packaging requirements. Furthermore, the filter technology can be readily assimilated into modern ASIC and FPGA-enabled designs.
