Synthesis of a superposition based FIR digital baseband filter
Earl McCune, Michael A. Soderstrand · 2002
The baseband filtering of digital data waveforms is considerably simplified by the use of superposition based filtering. This paper develops such a superposition based FIR filter from direct FIR filter structures. The resulting superposition FIR (SFIR) filter is shown to have no multipliers and only one adder, a significant simplification.
