Definition of amplifier

In its most general and comprehensive sense, amplifier means that it amplifies. An amplifier will then all that device that will magnify the amplitude of a phenomenon from the use of energy. While the Word applies principally to designate electronic amplifiers, there are other alternative types such as: mechanical, pneumatic and hydraulic.
The most common use, as well mentioned above, is linked to the appliance that allows you to enlarge the size of the sound. Amplifiers are teams that allow electric guitars to issue sound, since they do not have resonance boxes that do that work; strings vibrate on an electromagnetic capsule and vibrations will be amplified by the team.
Then, musical instrument amplifiers make interface as to give rise to the emission of sounds. In addition, through handling it is possible to add different sound effects, the most common include distortions.
In addition, TVs and radios have amplifiers built into their structures. In this case the amplifier can be handled using knobs or buttons arranged in the outer box of the device in question and from there vary the intensity of sounds according to the needs that you have.
Different types of physical and electronic amplifiers include the following: operational amplifier, differential amplifier, power amplifier, amplifier isolation, instrumentation amplifier, amplifier of light, optical amplifier and power amplifier. Although each is responsible for a specific function for which it was created, all respect the same mission: increase the intensity of the phenomenon in question.
