Gain, английский
- An increase in voltage or power, usually expressed in db.
- Any increase or decrease in strength of an electrical signal. gain is measured in terms of
- The electronic amplification factor of a signal.
- An increase in signal power in transmission from one point to another; usually expressed in decibels.
- Any increase or decrease in strength of an electrical signal. is measured in terms of decibels or number of times of magnification.
- A measure of the increase in forward transmitter power of an antenna or telescope with respect to that of an isotropic radiator. an antenna is said to have a "directivity" since it directs more energy in one direction. it is proportional to the aperture area of the telescope and inversely proportional to the square of the wavelength. even small optical telescopes can have very high gain, since the wavelength is so small. typically a 10 meter diameter visible telescope has a gain of about 1015 (150 db), while a 100 meter diameter microwave dish operating at 10 ghz has a gain of only 108 (80 db). this is a difference of a factor of 107 (70 db), i.e., 10 million times.
- A measure of the strength of optical amplification
- Gain refers to the relationship between the input signal and the output signal of any electronic system. higher levels of gain amplify the signal, resulting in greater levels of brightness and contrast. lower levels of gain will darken the image, and soften the contrast. effectively, gain adjustment affects the sensitivity to light of the ccd or cmos sensor. in a digital camera, this concept is analogous to the iso or asa ratings of silver-halide films.
- In carpentry, a groove or notch in one piece into which another piece is fitted. gain joint galerie surrounding a raised house galerie house, gallery house in french vernacular architecture, a farmhouse or plantation
- An act of adding or increasing something the baby showed a gain in weight of 25g or showed a weight gain of 25g. verb to obtain something, or to increase to gain in weight or to gain weight
- The figure of merit used to judge potential classification splits in id3, defined as the change in entropy by the split. it was replaced with the gain ratio criterion in c4.5. see also: c4.5.
- Also known as `amplification`, the ratio between the input voltage and the output voltage, or between the input power and the output power. gain is usually expressed in decibels.
- A profit on a securities transaction recognized by selling a security for more than the security originally cost. the gain is the difference between the cost and the sale.
- Amplification (especially of a signal)

Swell, английский
- Hinchazón, bulto
- Волна, волнение, усиление
- A rolling wave which seldom breaks unless it meets resistance, generally denoting a continuous heaving, which remains for some time after the wind which caused it has subsided. also, the gradual thickening of the muzzle of a gun, hounds of a mast, &c.
- Long unbroken heaves of the sea due to wind-generated waves that have advanced into calmer waters and acquired a more rounded form. because of their length, swell waves do not break. the stronger the winds at the source area, the bigger will be the swell and the further will it travel; and the longer the wind blows in the source area, the longer will the swell persist, even long after the wind has ceased or changed direction. experienced watch officers often report trains of swell waves, of differing periods and amplitudes, arriving simultaneously from two or even three directions.
- Large smooth waves that do not break. swells are formed by wind action over a long distance.
- Постепенное нарастание и ослабление звука

Magnification, английский
- The ratio of image to object size in an optical system. may be real (linear) or apparent (angular). milliradian (mrad)1/1000th of a radian, or 0.0573 degrees; the angle whose tangent is 0.001.
- The increase in the apparent or perceived size or subtended angle of an image in relation to actual size of object.
- Увеличение ~ of lens увеличение лупы
- The power of a microscope (or lens) to produce an image that appears larger than the actual specimen, expressed as a factor of the actual size
Увеличение, русский
