Communications engineers will aim to produce channels which assure clear and unambiguous signals, and to exploit the capacity of every channel fully. When a signal is sent out, there must be a code by which it may be interpreted. Various properties of different types of transmission channels have been identified in communications engineering such as noise, distortion, and redundancy. These properties can be measured and permit the engineer to compare and to evaluate the different channels available. Empirics concerns this transmission of signals, and their coding and decoding by interpreters. In this chapter we will explain the role of the physical and engineering aspects of information within the structure of semiotics.
