Term: Overshoot/Undershoot Definition: 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. The ringing is caused by an unmatched impedance load presented to the oscillator output. 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.
