Different Types and Applications of Amplifiers #digital_reviews

An amplifier is used to increase the amplitude of a signal, without changing other parameters of the waveform such as frequency or wave shape. Amplifiers are one of the most commonly used circuits in electronics and perform a variety of functions in a many electronic systems.

The amplifier symbol gives no detail of the types of amplifiers described, it only gives the direction of signal flow and can be assumed as flowing from left to right of the diagram. different types of amplifiers are also often described in system or block diagrams by name.
