The term overshoot has the following meanings: ELECTRONICS Signal .]] In Electronics "overshoot" can mean: 1. In the transition of any parameter from one value to another, the transitory value of the parameter that exceeds the final (steady state) value. ''Note:'' Overshoot occurs when the Transition is from a lower value to a higher value. When the transition is from a higher value to a lower value, and the parameter takes a transitory value that is lower than the final value, the phenomenon is called ''"undershoot"'' or ''"negative overshoot"'' See Gibbs Phenomenon . 2. The increased amplitude of a portion of a nonsinusoidal Waveform , ''i.e.'' Signal , at the Output of a nonlinear Circuit , ''e.g.'' a realizable amplifier, caused by the characteristics of the circuit. ''Note 1:'' Overshoot represents a Distortion of the signal. ''Note 2:'' Overshoot may result from circuit design parameters that are intended to decrease the Response Time of the circuit. ''Note 3:'' The amount of overshoot in a given Circuit is designed to minimize Response Time while maintaining Distortion of the Signal within acceptable limits. The absence or presence of overshoot, and if present, its magnitude, is a function of a circuit design parameter called ''" Damping ." See illustration under'' Waveform . 3. The result of an unusual atmospheric, ''e.g.'', ionospheric, condition that causes Microwave signals to be received where they are not intended.

AVIATION In . ECOLOGY In Ecology , overshoot occurs when a population exceeds the long term Carrying Capacity of its environment. The consequence of overshoot is called a crash or die-off. For a classic application of this concept to human experience, see Overshoot: The Ecological Basis of Revolutionary Change. Urbana: University of Illinois Press, 1980. ECONOMICS In Economics , it may refer to the Overshooting Model . |
