Design of Analog-to-Digital Transformations Tuned to the System Simulation

The selection of analog-to-digital transformations for the accurate digital simulation of continuous-time dynamical systems is considered here. A technique for optimizing this process is proposed, that involves "tuning" the transformation to suit the specific analog system or sub-system. An essential component of this process is a technique for fast and approximate stability analysis of characteristic equations, which can be performed by adapting a recent numerical technique to this problem.
