| 126 |  | Furse, Cynthia M. | Noise-domain reflectometry for locating wiring faults | Abstract-Reflectometry is commonly used to determine the integrity of cables and wiring. This paper describes a new family of reflectometers, the noise-domain reflectometers (NDR), that uses existing data signals on wiring and does not need to generate any signals of their own. There are two types o... | 2005 | |
