UNIFORM TRANSMISSION LINE

A transmission line that has distributed electrical properties, i.e., resistance, inductance, and capacitance per unit length, that are constant along the line, and in which the voltage-to-current ratio does not vary with distance along the line, if the line is terminated in its characteristic impedance . Note 1: Examples of uniform transmission lines are coaxial cables, twisted pairs, and single wires at constant height above ground, all of which have no changes in geometry, materials, or construction along their length. Note 2: In a uniform transmission line, signal attenuation is a function of the length of the line and the frequency of the signal. [ From Weik '89 ]
