Abstract :
The effect of a slight mismatch in the clock frequencies of a distributed feedback system is investigated. The stability behavior is analyzed and necessary and sufficient conditions for BIBO stability are derived. It is shown that stability of the synchronously operating feedback system can be lost for even extremely small frequency drifts, i.e. the synchronously operating system has no stability robustness with respect to clock frequency drifts.
