rise time


Also found in: Encyclopedia, Wikipedia.

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.

Made by Berkeley Nucleonics, a leading manufacturer of precision electronic instrumentation for test, measurement, and nuclear research, the Model 765 Fast Rise Time Pulse Generator is available now from Saelig Company, Inc.
To assess fundamental component rise time, one has to get rid of the ripple component of motor currents resulting from changes of inverter states in each PWM cycle.
In this section, the effect of the injected current, the FWHM of homogeneous broadening, and phonon bottleneck on the rise time, fall time, and the bit rate will be treated.
As a result, the CRF Series is optimized not only for RF signals, but also digital signals where the skew rates, or effects on the rise time of fast digital pulses, are less than 40 picoseconds through the relay.
As adolescents get older, they delay progressively their rise time and bedtime, sleep length decreases (see Gradisar, Gardner, & Dohnt, 2011), and sleep irregularity increases (Giannotti, Cortesi, Sebastiani, & Vagnoni, 2005; Laberge et al., 2001; Russo et al., 2007; Yang, Kim, Patel, & Lee, 2005).
With a rise time of 25 psec, typical of a high-end PCIe gen II part, and a coupled length of 2", the FEXT would be about 20%.
However, it was not the perception of the length of these notes that was shown to affect how succesful a child completed the task, but the child's perception of "rise time", which is the time it takes for a sound to reach its peak intensity.
First is the amount of time needed to impose this "instantaneous" strain, called the finite rise time. The second issue is that of transducer overloads and material rupture.
Each sensor is 100 percent in-process tested for resonant frequency, rise time, and acceleration compensation.
Any un-terminated trace that is left hanging can be a stub and, depending upon the rise time of the signal, can act as an antenna.
