Center clipper
| Telecommunications Glossary |
Variable attenuator which is used to eliminate any residual echo left by the echo canceller. a key difference between one canceller and another is the manner in which this center clipper operates. in a high quality canceller, the center clipper will operate very rapidly and smoothly, resulting in no residual echo during double-talk and no clipping of syllables. the center clipper is in essence a level- activated switch. signals above the threshold level are passed unaltered and signals below the threshold are blocked. when speech is present in both directions, the center clipper tends to mutilate the speech signal, adding audible amounts of harmonic and intermodulation distortion. this distortion is often referred to as glitch and sounds remarkably like its name when it occurs. the transmit signal can be totally chopped out if the level of the transmit signal drops below the estimated level of returning echo.

- 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
Difference, английский
- Disagreement, inequity, contrast, dissimilarity, incompatibility
- Разница; разность
- An important army term, meaning firstly the sum to be paid by officers when exchanging from the half to full pay; and, secondly, the price or difference in value of the several commissions.

- Раскреплённый связями в двух взаимно перпендикулярных направлениях
- In the maps application, instructions for how to get from one location to another, either driving or walking.
Intermodulation, 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

- 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

The unit of a computer that includes circuits controlling the interpretation and execution of instructions.
Cd-wo - compact disc-write once, английский
A term that describes compact discs that can be written to directly (rather than mass produced) with a laser recorder. recent developments allow the cd-wo to be appendable. cd-wo media is physically defined by the orange book standard, part ii, and a proposal for the logical format has been submitted to ecma by the frankfort group.
