3-52CHARACTERISTIC IMPEDANCE, Z0, is the ratio of E to I at every point along the line. Formaximum transfer of electrical power, the characteristic impedance and load impedance must be matched.The VELOCITY at which a wave travels over a given length of transmission line can be found byusing the formula:A transmission line that is not terminated in its characteristic impedance is said to be FINITE.When dc is applied to an OPEN-ENDED line, the voltage is reflected back from the open endwithout any change in polarity, amplitude, or shape. Current is reflected back with the same amplitudeand shape but with opposite polarity.
