Subsystems are represented in block diagrams as blocks, each representing a transfer function. In this unit we will consider how to combine the blocks corresponding to individual subsystems so that we can represent a whole system as a single block, and therefore a single transfer function. Block diagram - Wikipedia A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. They are heavily used in engineering in hardware design , electronic design , software design , and process flow diagrams .
