Damping transfer functions explained

WebCritical damping viewed as the minimum value of damping that prevents oscillation is a desirable solution to many vibration problems. Increased damping implies more energy dissipation, and more phase lag in the response of a system. ... Transfer functions represent the complex dynamic behavior of circuits but are an abstraction of actual ... 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.
