Refers to the ability of an amplifier's output to accurately reflect the input waveforms' rise time transients. An amplifier is said to have a slew rate of so many volts per microsecond. A slew rate of 20 volts per microsecond (20 V/U sec.) means that the amplifier is capable of swinging 20 volts positive or negative in the period of one microsecond.
the maximum rate which an amplifier's output can change, generally expressed in V/µs.
The measure of how fast a large signal can change. It is dimensionally expressed in terms of volts
This is how fast the output of a device (power amp) response to a given input. A fast slew rate is better. Large power amps generally have slower slew rates because of the greater amount of amplification required. It takes more time for the output to change at loud levels that it does at lower levels. This results in a lose in high frequencies as well as sound definition.
The rate at which a gradient may be turned on or off. The faster the slew rate the more possible it is for an MRI system to do EPI or fMRI, and the shorter the TE value that can be achieved in a spin echo sequence.
Refers to the ability of an amplifier's output to accurately follow the input waveform's level changes. Larger power amplifiers need a higher slew rate to maintain the same response to transients.
The specified (typically maximum) rate of change of a D/A converter or amplifier/buffer output. It is expressed in volts/microsecond.
maximum rate of change of output voltage from an op amp
This is a term used to describe how quickly the output of an amplifier can follow its input. Slew Rate is usually measured in V / msec. The higher the value, the better the amp is at reproducing the subtle nuances and dynamics associated with sound reproduction.
As applied in this paper it is the rate of change of the temperature chamber measured with a thermocouple secured to the PCA.
The maximum rate of change of an output signal.
The rate of frequency change per second. A typical rate for sensitive equipment is 1Hz/second.
Slew rate is the maximum rate at which a DAC output can change, or the maximum rate at which an ADC's input can change without causing an error in the digitized output. For a DAC with output amplifier, the specified slew rate is typically that of the amplifier.
SR V/uSec When the input is overdriven, such as with a square wave, the output of the ampfilier will slew at some maximum rate, usually spec'd in V/usec. Measured from the 10% to the 90% points of the output waveform. Also called Large Signal Response.
The maximum charge rate of the signal sampling capacitor in the sample and hold circuit of an A/D converter. It is expressed in volts/microsecond.
In a segment of the intracardiac electrogram, the amount of change in signal amplitude (voltage) divided by the period of time in which the change occurred. It appears graphically as the steepest slope of the waveform. Slew rate is usually expressed in mV per ms or volts per second. It is mathematically defined as dV/dt. Most pulse generator sense amplifiers require a slew rate of greater than or equal to 0.5 V/sec in order for a signal to be sensed.
The internally-limited rate of change in output voltage with a large-amplitude step function applied to the input.
In an image, the maximum speed of pixel to pixel change. For example, a black to white border might take several pixels to transition. The slew rate would be the most change between any two pixels of the transition.
The maximum rate at which the output voltage of an op-amp can change.
Slew rate measures the ability of a piece of audio equipment to accurately reproduce fast changes in amplitude. Measured in volts per microsecond, this spec is most commonly associated with amplifiers, but can bet applied to most types of equipment. In amplifiers, a low slew rate softens the definition of a signal, blurring transients and sounding "mushy." Slew rate is most critical in high frequencies reproduction where rapid changes in amplitude are most pronounced. An amplifier with a higher slew rate is often subjectively rated as tighter and more dynamic.
the amplifier's ability to react to quick changes in signal voltage. For amps rated up to 100W continuous, the slew rate should be at least 10V per microseconds. For amps over 200W continuous, it should be at least 30V per microsecond
In electronics, the slew rate is a nonlinear effect in amplifiers. It represents the maximum rate of change of signal at the amplifier output.
