Schematic Diagrams

When a circuit has more than one or two components, it begins to be difficult to clearly describe it using words alone. A simplified, stylized diagramming technique has been developed over the years to help facilitate this necessary form of communication. An electronic schematic diagram represents individual components as symbols, usually connected with solid lines to indicate the wiring connecting the components. See Figure 4-1.

Other technical occupations also have their own version of schematics. Any sort of stylized representation that focuses only on the essential components ...
