Finite wordlength effects in fixed-point 2-D digital filters

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The stability of 2-D digital filters implemented with two's complement quantization is investigated. The difference equation model is considered for the following cases: (i) quantization after each product, and (ii) quantization after a complete sum of products. For both cases, sufficient conditions are established for asymptotic stability. The 2-D state-space Roesser's model is also considered under two's complement quantization, and a sufficient condition is derived for its stability.
