	Tektronix: Oscilloscopes > Selection Guide - Rise Time
		Your oscilloscope must have sufficient rise time to accurately capture the details of rapid transitions.
		Notice that this basis for oscilloscope rise time selection is similar to that for bandwidth.
		where k is a value between 0.35 and 0.45, depending on the shape of the oscilloscope's frequency response curve and pulse rise time response.

	Rise time - LearnThis.Info Enclyclopedia (Site not responding. Last check: 2007-10-27)
		In electronics, rise time usually refers to the time it takes for a voltage to rise from 10% to 90% of it's peak value.
		Rise time (also risetime) values in a resistive circuit are primarily due to stray capacitance and inductance in the circuit.
		Due to differences in driving circuit power, rise time may or may not be equal to fall time.

	Physics of capnography
		The transit time is the time required for the sample to move from the point of sampling to the detector cell.
		Alternatively, rise time may be specified as T70 which is the time taken to change from 10% to 70% of the final value.
		The rise time is dependent upon the size of the sample chamber and the gas flow.

		The rise time, decay time and activation line width (ALW) were computed from the signal intensity curves for activated pixels in the sensori-motor cortex.
		The rise time is defined as the time from baseline to initial activation plateau for each activation period.
		The rise time appears to be a constant across the various activation periods while the decay time increases to a plateau.

	System Dynamics - Response Time
		One widely used measure of speed of response is the 10%-90% rise time, or the ten-to-ninety rise time.
		Rise time is going to be tough, so we're going to leave that definition as it stands.
		Settling time can be a good way to measure response time as long as care is taken to ensure that the response stays within 10% (or 5%?) of the final, steady-state value.

		The pulse width is specified as 100 nanoseconds wide, and the TLP tester rise time range is from 0.20 to 10 nanoseconds for both the voltage (open load) measurements and current (short load) measurements.
		Rise time is a parameter that reflects a storage instrument's ability to accurately record fast pulses.
		It appears that the higher bandwidth 5.0 GHz o-scope is the one ideal for measuring the rise time of the 200-picosecond input signal.

	IC Logic Device Slew Rate and Rise Time
		Slow rise times these days are considered to be longer then 50nS.
		However; Slow rise times could be produced by 3-state outputs which are not pulled high [for example], or devices which need to drive large capacitive loads.
		The rise time is then based on the RC time constant of the circuit, and the amount of current the IC can deliver.

		Settling time is the total elapsed time from input application until the output arrives at and remains within a specified error band around the final value (references 1, 2, and 3).
		The circuit's rise time is 360 psec, and its pulse amplitude is adjustable.
		The 360-psec rise time is almost three times faster than the 1-nsec rise-time pulse generator, which is the fastest of those that generated the data in Figure 2 and that promoted a 2500V/µsec slew rate.

		The observed rise time using the HP 54542A with the HP 10441A is approximately 1.57 ns.

	Technical Note 39 - Signal Rise Time
		The latter is a consequence of the higher connector resistance in the signal lead together with the internal capacity of the I.C. The result of increased rise times is an occasional system failure, as certain signal paths are not enabled by other timing signals, within the "windows" necessary to keep the equipment operating.
		Upon using the stabilant there was an average reduction in rise time of 40% with one contact having a reduction of 70% in its signal rise time.
		With very high speed memory applications or where very high rise times are encountered, it must be remembered that the capacitance between adjacent contacts is increased by the application of Stabilants on the socket insulation.

	GIS RTI (Site not responding. Last check: 2007-10-27)
		In particular, rise time rejection makes use of the fact that true X-ray events, unlike particle events, occupy a characteristic and tightly defined band on the pulse height (PHA)/rise-time plane.
		In effect, a second rise time window is applied the shape of which is the same as the region occupied by X-rays but the width of which is marginally larger.
		To avoid this, the second rise time rejection is performed, not in the PHA/rise-time plane, but in the PHA/RTI plane, i.e., the PHA/Rise Time Invariant plane.

	TIME-FREQUENCY RESOLUTION
		Tightness in the inequality (1) may be associated with situations in which a certain rise time is quickly followed by an equal decay time.
		Slackness in the inequality (1) may be associated with increasing inequality between rise time and decay time.
		To construct a time function with as long an autocorrelation as possible, the best thing to do is to concentrate the energy in two lumps, one at each end of the time function.

		If the rise in flow is not commensurate with patient demand, pressure may overshoot the set level (too rapid an increase in flow) or patient effort can be excessive (inadequate increase in flow).
		We evaluated the function of rise time on 5 new-generation ventilators and inspiration termination criteria on 2 new-generation ventilators.
		We hypothesized that there would be no differences in the operation of rise time between PS and PA/C modes on a given ventilator but that there would be large differences among ventilators evaluated.

		Suppose you have in your hand a skin-effect limited cable with a rise time of 1 nsec.
		According to the rule for transmission lines dominated by the skin effect (whose rise time scales with length squared), the rise time of each half-length piece should be 0.25 nsec.

	Time and the Observer
		At different times and different places, various "decisions" or "judgments" are made: more literally, parts of the brain are caused to go into states that differentially respond to different features, e.g., first mere onset of stimulus, then shape, later color (in a different pathway), motion, and eventually object recognition.
		She reported a mean response time over 9 subjects of 358msec, which, she argued, showed that the subjects must have achieved neuronal adequacy by the 200msec mark at the latest (allowing time for the production of a verbal response).
		The sense the subjects reported of not quite having had time to "veto" the initiated button push when they "saw the slide was already changing" is a natural interpretation for the brain to settle on (eventually) of the various contents made available at various times for incorporation into the narrative.
