rise time

1. the time required for a pulse or echo to rise from onset to its peak amplitude;
2. the time required for a pulse or echo to rise from 10-90% peak amplitude.

rise time

Therefore, as the mutual inductance gets larger (that is, as the trace gets closer to the plane and the characteristic impedances decrease), the overall loop inductance is reduced and the signal rise times get faster.
75 micron) cursor resolution, system rise times as low as 60 ps (20-80%, CT100HF), and horizontal range of up to 44,000 ft.
Finite rise times arise from the inability of a rheometer to instantly apply the desired strain to a material.
But due to comparatively longer rise times, the effect of over-voltage was not so critical with those devices.
This means that the data signal round trip travel time to the end of the bus has to be understood and treated as a critical parameter, which should be longer than the rise time of the data signal.
Each gate driver exhibits output rise and falls times under 25 nanoseconds with matched output rise times.
During the 53-year investigation, grip strength, standing balance, and chair rise times were measured as indicators of strength and physical performance.
As rise times shorten, it becomes vitally important to know how to achieve and maintain good signal integrity, including crosstalk, reflections, termination, placement and routing.
Reportedly reduces viscosity of the polyol mix, offers solvent properties to help disperse polyolmix components, and provides good latitude in adjusting cream and rise times.
Called the Agilent N1020A Options K12 and K13, the fixture delivers measurement bandwidth beyond 6GHz, with rise times well below 100 picoseconds (ps), which supports the margins required by HDMI Authorized Testing Centers.
The new dV Sentry(TM) filter reduces common mode voltage, peak voltage and rise times in one easy-to-integrate package to help protect AC motors, cables and drives against power quality problems
