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… WebEach of these waves have a voltage amplitude—the "forward" voltage V f and the "reflected" voltage V r. The conceptual problem comes from the dials of the directional wattmeter, which are not calibrated in volts but rather in watts. luchincy moon stuck sandals https://omnigeekshop.com
