Investigating the sensitivity of first-order recursive DSP networks
Kamelia S. Nikolova, Zlatka Valkova-Jarvis · 2016
In addition to diverse applications as separate digital systems, first-order DSP networks provide a basic design framework for cascade and other efficient filter architectures. The use of very low-sensitivity digital structures is a key approach to reducing the negative impact of quantisation on digital signal processing (DSP) system implementation. This publication presents the experimental results of an investigation into sensitivity at all possible placements of poles for some of the most commonly-used recursive first-order digital networks.
