Line driver

As a line amplifier, line driver also (of English linedriver) or extender, is referred to an electronic amplifier circuit to improve the quality in the transmission of electrical signals. The line amplifier boosts the level of a desired signal before being fed into a transmission line, and so compensates for attenuation losses and reduces interference because you can work at the other end of the line with a smaller gain due to the higher signal level of the amplifier is recommended. At the same time as the possible range of the transmission is increased.

Line driver are both in the analogue and in digital transmission and communication equipment - for example, antenna and CATV equipment - used. They also serve other purposes, to the deliberate signal distortion by overdriving subsequent amplifier stages, for example in guitar amps.
