An amplifier is an electronic device that is used in wireless communications and broadcasting and its used to increase the amplitude of a signal, therefore its name. It is a stable connection that does not change the frequency and shape of the waveform and there are two main types of amplifiers - power and weak-signal ones. However, this is not the only categorization for amplifiers. There are 5 main classes of amplifiers, each quite different from the other as they are set to be used for relatively specific reasons. When it comes to do-it-yourself amplifiers, one must know the difference between these classes and types in order to find out which one will be the most efficient to them.
