gain: A measure of signal amplification. It is usually given by the ratio of the output amplitude of a signal to its input amplitude. This could be its current, voltage or power. The ratio can be measured as a fraction, percentage or in decibels. A ratio greater than unity, 100% or a positive value of decibels indicates a gain. Ratios less than unity, 100% or a negative value of decibels indicates a loss.
gain-bandwidth product: A measure of the performance of an amplifier, it is given by the product of the gain and the bandwidth that it can handle. The unit of gain-bandwidth is hertz if the gain is measured as a fraction and the bandwidth is in hertz.
gain hit: Errors caused in data transmission due to signal surges. Usually this occurs when ...
