A block diagram is a representation of a system where the principal parts or functions are represented by blocks connected by lines that shows the relationships of the blocks. A power amplifier is an electronic amplifier designed to increase the magnitude of the power of a given input signal. A block diagram of a Power AMP shows the base of the transistor and how the size of the transistor is made larger, in order to dissipate more heat, which is produced during transistor operation. As shown, a power AMP block diagram is a sequential circuit designed to accept multiple inputs. EdrawMax and EdrawMax Online let you the best way to create power AMP block diagram examples for your projects.
