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).
What is grounding and what protection does it offer? âGroundingâ a tool or electrical system means intentionally creating a low-resistance path that connects to the earth. This prevents the buildup of voltages that could cause an electrical accident. Grounding is normally a secondary protective measure to protect against electric shock. It does not guarantee that you wonât get a shock or be injured or killed by an electrical current.
