There are several approaches to understanding reflections, but the relationship of reflections to the conservation laws is particularly enlightening. A simple example is a step voltage, (where is the height of the step and is the unit step function with time ), applied to one end of a lossless line, and consider what happens when the line is terminated in various ways. The step will be propagat… holiday inn sunland park el paso txWebA transmission line that is terminated in some impedance, Z L, that is different from the characteristic impedance, Z 0, will result in a wave being reflected from the termination back to the source.At the input to the line the reflected voltage adds to the incident voltage and the reflected current subtracts (because the wave is travelling in the opposite direction) … huis finlandWebQuestion: Zin =Z0Z0+jZLtanhγlZL+jZ0tanhγlThe power radiated from a lossless antenna is given as 10 W.
