Threshold, английский
- Seuil
- The smallest input value to a sensor which will cause the sensor to respond. commonly used with mechanical wind sensors to describe the wind speed necessary to cause the anemometer and wind vane to turn.
- The bottom metal or wood plate of an exterior door frame. generally they are adjustable to keep a tight fit with the door slab.
- Порог, точка, в которой процесс начинается или изменяется. пороговые установки при сканировании черно-белых изображений определяют, какие пикселы должны быть сконвертированы в черные, а какие с в белые. в нерезком маскировании порог определяет, каким долж
- Порог; пороговое значении
- Порог; входная кромка впп
- A defined pass or fail value, i.e., the maximum or minimum value of insertion loss in db or dbm
- The input level at which lasing begins during excitation of the laser medium.
- Лимит, предел
- 1. the point at which something starts, e.g. where something can be perceived by the body or where a drug starts to have an effect she has a low hearing threshold. 2. the point at which a sensation is strong enough to be sensed by the sensory nerves ‘…if intracranial pressure rises above the treatment threshold, it is imperative first to validate the reading and then to eliminate any factors exacerbating the rise in pressure’ [british journal of hospital medicine]
- Порог; пороговая величина; предел
- The beginning of the part of the runway usable for landing
- Порог. характерный признак, значимая величина, уровень или предел, при которых начинает происходить или возникать некое событие. см. cut-off concentration (критическая концентрация).
- Порог. см. nuisance threshold; odour threshold — порог вредного (нежелательного) воздействия; порог ощущения запаха. •...¦`" --¦:.
- In a compressor or limiter, the input level above which compression or limiting takes place. therefore the level of the audio must be above the threshold setting, or no effect is heard. in an expander or gate, the input level below which expansion or gating occurs.
- A filter effect in windows movie maker.
- A limit against which other values can be compared. when a value crosses this limit, it can trigger an alert or other action.
- Порог. характерный признак, значимая величина, уровень или предел, при которых начинает происходить или возникать некое событие. см. cutoff concentration (критическая концентрация).

- Since color in the scanned images of colored documents is rarely even, a threshold value is often needed when defining colors for individual fields. the threshold value determines the size of the range of colors that entrance will accept in relation to the reference color. on a scale of 0-100, a value of zero will only accept exact matches of the reference color, whereas with a value of 100, will include a much broader range of colors. the default value is 50 and is sufficient in most situations.
- In reference to currents or magnetic fields, the minimum strength necessary to create a lookedfor effect is called the threshold value. for example, the minimum current necessary to produce a readable indication at a given defect, is the threshold value of current for that purpose.
- A value in a phenomenon where a large change of output occurs.
- Setting of an instrument that causes it to register only those changes in response greater or less than a specified magnitude.4 see adaptive thresholding, resolution threshold.
- Voltage level setting of an instrument that causes it to register only signals greater or less than a specified magnitude.10,20 this threshold may be adjustable, fixed or floating.16 through-transmission technique: test technique in which ultrasonic energy is transmitted through the test object and received by a second transducer on the opposite side. changes in received signal amplitude are taken as indications of variations in material continuity.7
