A measure of the time required for the output voltage to change from a low voltage level ("O") to a high voltage level ("1") once a level change has been started.

tr The time for the output current of a photodiode to rise from 10% to 90% of final level in response to an instantaneous rise in input light power.

a measure (10% to 90%) of the time required for an output voltage to rise from a state of low voltage to a high voltage level, once a level change has started.

A measure of the steepness of the loading edge of a pulse, ie. it is the time taken for the instantaneuous amplitude to change from 10% to 90% of the peak value.

The time it takes for output to rise from low values, say 10%, to high values, say 90% of peak power.

The time necessary for the fluid to turn on. The rise time is usually shown on a graph that shows how the opacity of a segment increases over time after the drive signal is applied. Usually expressed in milliseconds.

The time required for a signal to change from a low level (usually 10%) to a high level (usually 90%) of its base line-to-peak or peak-to-peak amplitude. See also Fall Time.

The length of time required for a system to first arrive at the final steady state value in a transient analysis.

The duration (normally specified in milliseconds or optionally by the number of cycles of the tone) of that part of a stimulus tone envelope whose amplitude rises from zero to the full value. In cortical ERA the rise usually has a linear slope though a more complex transition may be used to maximise the frequency specificity of the stimulus. Traditionally, the fall time is the same as the rise time.

The time required for a signal to go from 10% to 90% of its maximum amplitude level.

The time interval of the leading edge between the instants the value reaches a specified lower and upper limit. This may be either from 10% to 90% (normally) of the peak value, or of the steady state value. Both definitions are used, thus causing confusion. NEMA uses the steady state value. Values of 70-100 ns (nanoseconds) are common for the latest IGBT controls; values of 200-300 ns are seen on older controls.

The amount of time it takes the output voltage to go from Logic '0' to logic '1'.

The time taken for a signal to make a transition from one state to another; usually measured between the 10% and 90% completion points of the transition. Shorter or faster rise times require more bandwidth in a transmission channel.

The time required for a component or logic circuit to change from the quiescent to the transient state when an input is applied. (i.e. elapsed time between application of input and attainment of full output level).

The length of time it takes a step-function, at the output of a filter, to move from 10% to 90% of its steady state value on the initial rise.

The elapsed time from a detector's first detectable signal in response to the presence of product to an output that is 95% of full scale for a quantitative detector or activated for a qualitative detector.

Measurement of the time elapsed during the current output change from 10 to 90 percent in a photoconductor.

Time for the leading edge of a pulse to rise from 10% of its peak value to 90% of its peak value.

The time it takes an output to rise from low levels to peak value. Typically measured as the time to rise from 10% to 90% of the maximum light output.

The time required for a signal to change from a small percentage (usually 10%) to a large percentage (usually 90%) of its peak-to-peak amplitude. See also FALL TIME.

The time required for a sensor or system to respond to an instantaneous step function, measured from the 10% to 90% points on the response waveforms.

The time required for the leading edge of a pulse to rise from 10% to 90% of its amplitude; the time required for a component to produce such a result. "Turn-on time."

Rise time of a square pulse is defined as the shortest time required for the voltage level to change from a "low" state to a high "state". Time is measured between voltage levels 10% and 90% of the "high" amplitude.

The time taken for the leading edge of a pulse to rise from its low to its high values, typically measured from 10% to 90%.

Usually, the time required for a pulse to increase from 10% of its final value to 90% of its final value. Rise time is less frequently measured between the 5% and 95% points or the 1% and 99% points. Rise time is used to specify the transient response of an instrument, and is similar to its time constant, relaxation time, or response time, although these latter terms use (1 − −1), or about 63%, as the fractional change in state over which time is measured, beginning at an initial value. For example, if a step increase of 10° is applied to a thermometer registering 0° with a rise time of 50 s, the thermometer would increase from 1° to 9° in 50 s. Note that nothing is specified concerning the time required for the instrument to respond to the first or last 10%. See also time lag.

The time interval required for a pulse to change from 10% to 90% of its amplitude. The time required for a BJT to go from cutoff to saturation; measured as the time required for I to rise from 10% to 90% of its maximum value.

The time required by the video amplifier of the projector to increase its output from 10% to 90% of the maximum value.

The time it takes for a signal to rise from a defined minimum to a fraction of the maximum signal. The low and high points are commonly defined as 10% to 90% of the maximum signal output.

In electronics, when describing a voltage or current step function, rise time (also risetime) refers to the time required for a signal to change from a specified low value to a specified high value. Typically, these values are 10% and 90% of the step height. The output signal of a system is charactezed also by fall time: both parameters depend on rise and fall times of input signal and on the characteristics of the system.
