A composite symbol is created by combining what types of symbols?

A composite symbol is created by combining basic symbols into a single symbol, which serves to streamline and simplify diagrammatic representations. This approach allows for greater clarity and ease of understanding when interpreting complex schematics. By merging multiple basic elements into one composite symbol, users can quickly identify system components and their interactions without being overwhelmed by individual symbols representing each component.

This method is particularly beneficial in technical drawing and circuit design, where efficiency in communication and visual representation is critical. Composite symbols help maintain a tidy layout, reduce clutter, and enhance the readability of schematic diagrams, allowing technicians and engineers to focus on functional relationships rather than on individual symbol meanings.

In contrast to other options, combining complex and simple elements (as stated in the first choice) or mixing basic and advanced symbols (as in the second option) does not typically yield a composite symbol in standard practices. The fourth option of special and common symbols does not accurately reflect the process of creating a composite symbol, as the focus is on the basic elements rather than differing complexities or commonality.
