Introduction We consider the realization of linear, shift–invariant, discrete–time systems in this Chapter. We will: Develop computational structure for various linear, shift–invariant, discrete–time systems. Develop one or more difference equations that can be used to compute the output sequence for an arbitrary input sequence for the linear, shift–invariant, discrete–time system. C. Williams & W.

Introduction Therefore, it is of interest to consider the alternate forms for the realization of digital filters. We consider the different realizations for discrete–time systems in this Chapter. C. Williams & W. Alexander (NCSU) IMPLEMENTATION OF SYSTEMS ECE 513, Fall 2017 7 / 214

Structures for FIR Systems In general, a FIR system can be described by a finite difference equation that involves only inputs and no previous outputs to compute the output.
