Abstract: We review how Shannon's classical notion of capacity is not enough to characterize a noisy communication channel if we intend to use that channel as part of a feedback loop to stabilize an unstable scalar linear system. While classical capacity is not enough, another parametric sense of capacity called "anytime capacity" is shown to be necessary for the stabilization of an unstable process. The rate required is given by the log of the unstable system gain and the sense of reliability... (Update)
