Definition of "Critical Damping" |
Critical damping of a measuring instrument causes the equilibrium deflection to be reached in the shortest possible time, with the oscillations of the needle being quickly damped out. [Note: Under damped instruments have their needles oscillating for some time, while over damped instruments take a long time to reach the final equilibrium deflection] / The amount of damping that prevents overshoot. See Damping for a graphic. An operation that is not underdamped or overdamped. / Critical damping of a measuring instrument causes the equilibrium deflection to be reached in the shortest possible time, with the oscillations of the needle being quickly damped out. / Critical damping is an influence within or upon an oscillatory system that has the effect of reducing, restricting or preventing its oscillations. In physical systems, damping is produced by processes that dissipate the energy stored in the oscillation. / A printed circuit board mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. PCBs can be single sided, double sided or multi-layer. Conductors on different layers are connected with plated-through holes called vias. Advanced PCBs may contain components - capacitors, resistors or active devices - embedded in the substrate. / the least amount of damping such that the system does not freely oscillate. |
