ABSTRACT

This chapter deals with transmission lines and wave propagation primarily from an engineering-mathematical point of view, and emphasizes aspects of importance in communication systems. It considers the growth of the surrounding technological pattern. The chapter describes Fidelity is a key objective for any communication system. The output should resemble the input closely enough that the forwarded information may be correctly understood, and, for audio applications, that the aesthetic qualities of speech, music, and sound effects, natural or simulated, may be preserved. The chapter describes electromagnetic-energy propagation along transmission lines will be considered initially in terms of voltage and current waves travelling on two uniform conductors. It analyses a frequency-domain (Laplace transform) approach is in order when the voltage and current response on a lossy line is to be found for excitation conditions other than sinusoidal steady state. Maxwell's equations, states that relationships among electromagnetic fields, from which the manner of field propagation in a given geometrical situation may be derived.
