The amount by which the revenue of a business exceeds its cost of operating.
The amount of amplification used in an electrical circuit. Gain is usually measured in decibels, but it can also be expressed as the ratio of output power to input power.
In electronics, the ratio of the amplitude of the output signal produced by an amplifier to that of the input signal. In a voltage amplifier the voltage gain is the ratio of the output voltage to the input voltage; in an inverting operational amplifier (op-amp) it is equal to the ratio of the resistance of the feedback resistor to that of the input resistor.
The increase in the amplitude of a signal, as of voltage, current, or power, that is produced by a circuit. Gain can be expressed as a factor or in decibels. See also decibel.
