Abstract :
The best measure quantifying FWL (finite word length) stability is the one that bases on the largest stable perturbation hypercube. But the computing of this FWL stability measure has not been solved. For second order digital systems, this paper develops an analytic computing method. Through solving 12 linear equations and 12 quadratic equations, the measure value can be obtained exactly.
