This presents various types of amplifiers and their functions. Amplifiers are electronic devices that increase the strength of an electrical signal. This includes common amplifier types such as simple amplifiers, amplifiers with external DC control, operational amplifiers, controlled amplifiers, summing amplifiers, amplifiers with bypass, magnetic amplifiers, and box amplifiers. Each amplifier type is associated with a symbol and a brief description of its function, providing a quick reference for understanding the different amplification techniques and their applications in electronic circuits.
