Explanation of what a transmission line is, and the conditions under which it exists. Uses lumped element model to derive differential equations and manipulates the equations to get telegraph equations. Uses solutions to telegraph equations to get characteristic impedance and propagation constant and looks at matched and unmatched load cases.
