Facets:
Source sentences:
text: The reason is that when impedances are mismatched, the mismatch causes portions of the signal to reflect -- this can happen at the source, at the connectors, at any point along the cable, or at the load -- and when a portion of the signal bounces backward down the line, it combines with and interferes with the portions of the signal that follow it.
