A look through into the  Amplifiers

Amplifiers or an amp as the name suggests amplifies the weak signals into stronger ones. In simple terms, it boosts the electrical signals. Amplifiers are the only solution to increase both the current and the voltage. These are also applied in musical instruments such as the guitar. Amplifiers such as transistor, vacuum tube or valve, fully differential and operational are used for particular purpose. Earlier amplifiers were normally used in appliances such as telephones, radios and TV.  Later amplifiers were commonly used to amplify sound waves of low frequency. These are called as subwoofer amplifiers. The use of amplifiers are restricted to only control the volume of sound.

Later technology developed and the role of the amplifier was elaborated. Now that the amplifiers are used not only to boost the sound signals but also to bring out the clarity to the contents. By adjusting the amplifier, listeners can add accent to vocal messages or contents in a stage programme or to the background instrument music.

Amplifiers these days are made of solid-state electronics although some are made of vacuum tubes. Electrical noise is reduced by the use of toroidal transformers for power supply.

Now lets go through various types of amplifiers. Few electronic amplifiers are power amplifier, transistor amplifier, vacuum tube amplifier, operational amplifier, video amplifier, fully differential amplifier, microwave amplifier and musical instrument amplifier. And few other amplifier types are carbon microphone, rotating electrical machinery amplifier, magnetic amplifier, optical amplifer,mechanical amplifier and Johnsen-Rahbek effect amplifier.

Some important features of an amplifier are Linearity, Noise, Gain and Dynamicrange. Linearity measures the proportionality of the output signal to the input signal. Noise is referred to as the amount of unwanted interference or static that is added by the amplifier to the input signal. Gain is the ratio of the power of the input and the output. Dynamicrange is the part of the output signal that is useful. It lies in between the distortion and the noise levels.

Sky is the limit for the development and researches done in Science and Technology. So one can surely expect amplifiers to be used in further more number of  applications.
