An increase or amplification.

There are two general uses of the term in radar meteorology: 1) antenna gain (or gain factor), which is the ratio of the power transmitted along the beam axis to that of an isotropic radiator transmitting the same total power; and 2) receiver gain (or video gain), which is the amplification given a signal by the receiver.

    Any increase or decrease in strength of an electrical signal. Gain is measured in terms of decibels or number of times of magnification.

  • "Gain": In audio, the ratio of output level to the corresponding input level for a device. Level is typically represented in terms of power or voltage, but gain is unitless and is identical whether voltages or powers were used to calculate it. Because gain is a ratio, it is usually described using decibels. A gain of 0 dB indicates no change in level, while a gain of 10 dB is perceived as approximately a doubling in loudness—depending on the nature of the sound and on the initial loudness.
