Coaxial Cable Properties Introduction Coaxial cable is used for pulse transmission, where the wire and shield (separated by a dielectric) serve as a waveguide allowing small signals to be transmitted with minimal distortion. It has characteristic impedance (Z), capacitance (C), and inductance (L). The formulas for capacitance and inductance are:Self-Inductance of a Coaxial Cable.
