- In an ultrasonic transducer, the piezoelectric crystal to be coupled to the test surface. also called the crystal. transducer, flat response: transducer whose frequency response has no resonance or characteristic response within its specified frequency band. the ratio between the upper and lower limits of the frequency band are typically not less than 500 khz. transducer, resonant: transducer that uses the mechanical amplification due to a resonant frequency (or several close resonant frequencies) to give high sensitivity in a narrow band, typically ±10 percent of the principal resonant frequency at the –3 db points. transducer, wide band: transducer whose response to surface displacements is relatively flat over a broad frequency range.

Sensitivity, английский
- Change in the response of a measuring instrument divided by the corresponding change in the stimulus (1)
- The ratio of the output of an instrument to the input (i.e. -gain).
- Defines the smallest signal detectable in the presence of systems noise
- In television, a factor expressing the incident illumination upon a specified scene required to produce a specified picture signal at the output terminals of a television camera.
- For a camera usually specified in lux to provide indication of light level required to gain a full video signal from the camera.
- A measure of the amount of light required to provide a standard video signal. sensitivity values are stated in lux (see lux) or foot-candles.
- Lens iris aperture required to provide a video output signal of standard level at a specified light input. in general, sensitivity is measured using an 89.9% reflectance grey scale chart illuminated by a 3200? k illuminance at 2000 lux (color camera) or 400 lux (b/w camera), for a video output level of 100%.
- 1. the fact of being able to detect and respond to an outside stimulus 2. the rate of positive responses in a test from persons with a specific disease. a high rate of sensitivity means a low rate of people being incorrectly classed as negative. compare specificity

- The sensitivity of classification rule is a measure of its ability to correctly classify observations into a particular category. it is defined to be the ratio of the number of true positives to the number of positives in a test set. this value is usually inversely related to the specificity of the test for a given set of data and a particular classification rule. note that this measure is different from the positive predictive value of a rule, which is a measure of the probability that a positive is a true positive. if multiple classification categories exist, each category will have its own sensitivity, specificity, and positive predictive value. see also: positive predictive value, specificity.
