An amplifier is a device that boosts the strength of an electronic signal. Electrical signals become lower in amplitude, or "attenuated" as they travel through conductors in systems. When two integrated circuits on a circuit board are coupled by signal conductors on the circuit board, an electrical signal transmitted by one integrated circuit may be received as an attenuated signal by the other integrated circuit. Amplifiers add gain to the signal by an amount equal to the loss in the previous section of the network since last amplification. Amplifiers are used to boost electrical signals in many electronic devices, including radios, televisions, and telephones. The most common types of amplifiers are electronic and have transistors or electron tubes as their principal components.
