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).
Grounding electrode or ground electrode: a metal conductor, usually a solid copper-alloy rod of specified length, driven into the ground in order to provide a point for electrical connection between the building grounding system and ground or earth.n an electrical circuit the grounded conductor (white or neutral wire) normally carries electrical current between the un-grounded (hot) electrical wire and (back through the main electrical panel and grounding system) earth.
