On the suppression of zero-input parasitic oscillations in floating point wave digital filters

Fettweis [1] has given a condition which guarantees, if satisfied, the absence of zero-input parasitic oscillations in wave digital filters. In this paper a method is given which can be used to implement this condition in the case of floating point arithmetic.
