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).
Ground rings provide a. low impedance path from the grounding system to the earth itself, and a convenient means to. connect various grounding conductors to the grounding electrode system. Ground rings are. required to be a minimum of 20 feet in length, not smaller than 2 AWG, and buried not less than.
