Abstract :
A quantitative stability condition for a sampled-data feedback system is formulated. The system is obtained from a stable continuous-time feedback system by digitalization of the controller. The condition shows how to determine a sampling frequency f/sub 0/ such that for all f larger than f/sub 0/ the discrete-time system remains stable.
