About Amplifier

An amplifier is an electronic device that uses small amount of energy to control a source of larger amount of energy. It can be characterized on a lot of parameters such as gain, how much the amplifier increases the signal level, it is measured in decibels (dB), output dynamic range (the range between lowest useful output and largest useful output), Bandwidth (difference between the lower and the upper half power points) and rise time (the time taken for the output to change from 10% to 90% of its final level driven by a step input), noise, efficiency, linearity etc. One common type of amplifier is electronic amplifier; it is a device to increase the power of the signal. It takes power from the power supply and controls the output to match the input signal shape however with larger amplitude. It is commonly used in radio, television transmitters, micro computers, electronic digital equipments, guitars and instrument amplifiers. Its critical components are active devices such as vacuum tubes or transistors. The first instrument amplifier was guitar amplifier designed to use with electric amplifiers. They come in two main forms, the combo amplifiers that contain the amplifier head and guitar speaker in a single unit and in the other form of the amplifier the amp head is separate from the separate and joined to them by cables. Now a days there are different types of instrument amplifiers, Traditional guitar amplifier, hard-rock style guitar amplifiers, Bass amplifiers, Acoustic amplifiers and Keyboard amplifiers.
