 * 2) Detune a transmitter to match the load
 * 3) Guide electrical energy from point to point
 * 4) Replace the antenna in a communications system

3-2. The conductance value of a transmission line represents which of the following values?

3-7. A measurement of the voltage to current ratio (E$in$I$out$ at the input end of a transmission ine is called the
 * 1) input-gain. rate
 * 2) voltage-gain ratio
 * 3) output impedance
