Document Summary
Lec 4 9-1-16 ch 2 transmission lines / lumped. Element model / finding voltage and current at. We count the length with respect to wavelength. If is very large then the transmission line cannot be ignored and it will be. If is very small then the transmission lines can be ignored. Very large means greater than or equal to 100. Very small means less than or equal to . 01 accounted for as part of the circuit. Just how the symbols that are used to represent circuit elements only represent the functionality of the elements and not the physical shape, so will the lumped-element model for transmission lines. Transmission lines will be represented by a parallel wire configuration regardless of its specific shape or constitutive parameters. Lines will be oriented along the z directing and subdivided into differential sections each of length . Each section will be represented by an individual.
