- Ослабитель (сигнала); подавитель (колебаний); магазин затухания а/т auto throttle автомат тяги
- Ослабитель (сигнала); подавитель (колебаний); магазин затухания
- Ослабитель; подавитель
- A device for reducing the amplitude of a signal.
- A circuit that provides reduction of the amplitude of an electrical signal without introducing appreciable phase or frequency distortion.
- A component that incorporates a specific amount of loss into an operational optical network. s also provide a safety margin in planned networks to allow for electronics degradation over time, or physical changes to the optical component portion of the network. s come in two styles, fixed and variable. variable optical attenuators are used for testing systems for dynamic range and quality of signal testing
- 1) in electrical systems, a usually passive network for reducing the amplitude of a signal without appreciably distorting the waveform. 2) in optical systems, a passive device for reducing the amplitude of a signal without appreciably distorting the waveform.
- Аттенюатор; развязка; ослабитель мощности
- In a mixing console, an adjustable resistive network that reduces the microphone signal level to prevent overloading of the input transformer and mic preamplifier.
- A device that causes a known loss in energy of a beam that is passed through it. it may be calibrated in decibels.
- Device for varying the signal amplitude on an ultrasonic instrument. usually calibrated in decibels.7,21 b

Аттенюатор, русский
(от франц . attenuer - ослаблять), радиотехническое устройство (напр., в виде волновода или электрической цепи из резисторов) для понижения напряжения или мощности сигнала.
Sound . atterberg limits in plastic soils, the water contents (determined by standard tests) which define the boundaries between the different states of consistency of plastic soils. also, английский

Distortion, английский
- A drying defect caused by the differential shrinkage along the three axes of a piece of wood. distortion may take the form of cup, bow, twist, spring or diamonding.
- Искажение, дисторсия
- The deviation of the received signal waveform from that of the original transmitted waveform.
- Nonproportional representation of an original.
- Искажение (формы); коробление
- Нарушение достоверности информации, см. bias; error, deviation, misreporting запасы (сырья и материалов), см. stocks with industrial consumers; reserves for manufacturing purposes al consumers; reserves for manufacturing purposes 61,. distributed stocks (of raw materials) — производственные запасы (сырья и материалов), см. stocks with industrial consumers; reserves for manufacturing purposes.
- An undesired change in wave form of a signal in the course of its passage through a transmission system.
- An off-axis lens aberration that changes the geometric shape of the image due to a variation of focal length as a function of field angle.
- Any changing of line, form, or even light by photographic materials, such as lenses, films, or filters. though most designers do all they can to eliminate distortion from lenses, most photographers take the "if you can`t beat `em, join `em" approach and exploit it wherever they find it; they use distortion as part of their visual expression.
- An aberration which occurs as light rays move from the center of the lens toward the periphery. as rays approach the edge, the lens’s increasing magnification causes a distorting of the image.
- The act of twisting part of the body out of its usual shape
- Искажение
- N псхл. искажение
- Расхождение; несовпадение; искажение; искривление
- An intentional desired, or unintentional unwanted, change in the audio waveform, causing a raspy or edgy sound quality.
- Changing incoming information in some way.

Degradation, английский
- Dégradation
- The progressive failure of a machine or lubricant.
- Disintegration of a paint film by heat, moisture, sunlight, or natural causes.
- Debasement and disgrace. the suspension of a petty officer from his station; and also the depriving an officer or soldier of his arms previous to his being delivered over to the civil power for execution.
- In computer systems, a reduction in level of performance or service. degradation in microcomputer performance is indicated by slow response times or frequent pauses for disk access because memory is insufficient to hold an entire program plus the data the program is using.
- The loss of desirable physical properties by a textile material as a result of some process or physical/chemical phenomenon.

- A composite color video signal. the signal has composite sync, reference burst and a black video signal, which is usually at a level of 7.5 ire (50 mv) above the blanking level.
Differential phase, английский
- A change in the sub-carrier phase of a video signal caused by a change in the
- A change in the sub-carrier phase of a video signal caused by a change in the luminance level of the signal. the hue of colors in a scene change with the brightness of the scene. 11 / 43
