Block Diagram Examples

A block diagram is a great way to show a high-level overview of a system or methodology, particularly for engineering projects. This page provides examples for different types of block diagrams: a basic diagram, a computer system diagram, and a communication system diagram.

Using a block diagram

A block diagram isn’t meant to show every aspect of the system it represents. When you make one, it’s best to keep it relatively simple. You should use only blocks and lines as your diagram components. Make sure you illustrate what’s most important about the system you are trying to capture. It’s helpful to remember that each block in the diagram serves as a “black box.” You can know the input and output of the block, but the diagram doesn’t show the equations that led us there.

To get a better idea of how your block diagram should look, choose one of the examples below. Each example also serves as a template that you can edit with Lucidchart’s software.

Engineering with Lucidchart

Lucidchart is a great choice for engineering students and engineers. A single Lucidchart accounts grants you access to more than just block diagrams. Find templates and shape libraries for circuit diagrams, lean manufacturing tools, and much more.
