Damping is an influence within or upon an oscillatory system that has the effect of reducing or preventing its oscillation. In physical systems, damping is produced by processes that dissipate the energy stored in the oscillation. Examples include viscous drag (a liquid's viscosity can hinder an oscillatory system, causing it to slow down; see viscous damping) in mechanical systems, resistance in electronic oscillators, and absorption and scattering of light in optical oscillators. Da… WebIn the absence of a damping term, the ratio k=mwould be the square of the angular frequency of a solution, so we will write k=m= !2 n with! n>0, and call ! n the natural …

The damping ratio is a dimensionless quantity charaterizing the rate at which an oscillation in the system's response decays due to effects such as viscous friction or electrical resistance. From the above definitions, WebThose large values explain why exactly we use a decibel scale to measure the output of the transfer function. A decibel (dB) function is typically equal to \(dB(x) = -20\log_{10}(x)\) Understanding that we measure the transfer output on a log scale is very important, and you will see why in a second.
