Retirement ceremonies can be planned and executed by any Project Officer/NCO using this checklist. Deviations. may be necessary to tailor the ceremony to the individual, but the major items are included.
The ground is used for common mode rejection. The primary purpose of the ground is to prevent power line noise from interfering with the small biopotential signals of interest. By design, amplifiers should not be affected by large changes in potential at both the active and reference sites. A ground electrode for EEG recordings is often placed on the forehead (but could be placed anywhere else on the body; the location of the ground on the subject is generally irrelevant).
The design of a grounding rod consists of a long rod made of conductive material such as copper which is driven into the ground. A length of eight feet (approximately two and a half meters) is standard, with the rod being fully driven into the ground so that it does not present a tripping hazard. Once the grounding rod is placed, it can be connected to the electrical system with the use of a ground connector and a wire. Often, grounding rods are placed near an electrical box for convenience.
