Abstract :
The notions of a ∈-dimension and ∈-entropy were introduced into feedback theory of G. Zames (1976, 1979), who proposed them as measures of the complexity of identification and the effectiveness of feedback in reducing identification costs. The 1979 paper was concerned mainly with continuous-time systems, but also included a summary of discrete-time results which contained certain errata. The authors elaborate the discrete-time case, supply some omitted proofs, and correct the errata
