The approach to DSP adopted in this white paper is intended to instill confidence in designers who are implementing DSP algorithms in their designs, resulting in more efficient hardware implementations. Rather than beginning with mathematical descriptions of a system, designers can learn how simple functions in the analog world can be modeled and then can convert those functions into digital representations.
