This effect is commonly called ringing. The output voltage can exceed the steady state plateau of either the logic "0" state or the logic "1" state for a period of time. This ringing will decrease in amplitude until the steady state plateau is reached. An unmatched impedance load presented to the oscillator output causes the ringing. It becomes more pronounced as the rise/fall times decrease and the output frequency increases. Proper output loading and good R.F./Microwave transmission line techniques must be used to prevent ringing on the waveform.
The transient period of increased negativity at the termination of an action potential.
Transient change in a converter output voltage that does not meet the lower limit of the voltage accuracy specificiation. Typically occurs at converter turn on/off or with some step change in output load or input line. Also see Voltage Accuracy.
A transient change in output voltage, below output accuracy limits, that can occur when a power supply is turned on or off, or when there is a step change in line or load.
A form of transient distortion of a step or pulse signal in which the response makes a temporarily excursion before the main transtion and in the opposite direction.
Undershoot is the amount that an output falls under its final value after a sudden change in load.
The amount by which an output falls below its specified value in response to a rapid load change.
Undershoot refers to the amount by which voltage or frequency drops below the nominal value as the voltage regulator or governor responds to changes in load.
A transient output voltage change which does not meet the low limit of the voltage accuracy specification and is caused by turning the power supply on or off, or abruptly changing line or load conditions.
