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)

- Art networks have two non-specific gain control signals, g1 and g2 for the f1 and f2 layers, respectively. g1 implements the 2/3 rule in the f1 layer, while g2 enables/disables the f2 layer. see also: art, ftp:://ftp.sas.com/pub/neural/faq2.html, http://www.wi.leidenuniv.nl/art/.
