Abstract :
The paper begins with a restatement and proof of a tight bound on the data capacity a feedback channel must provide in order to stabilize a tight half-plane pole. This sets the stage for a treatment of some of the issues arising in the source coding of signals between controllers and plants in systems where feedback loops are closed using bandwidth limited communication links. In particular, we are interested in the qualitative dynamics of LTI feedback systems operating near the data-rate limit.
