Examples of Electronic Schematic Diagrams
Electronic schematics use symbols for each component found in an electrical circuit, no matter
how small. The schematics do not show placement or scale, merely function and flow. From this,
the actual workings of a piece of electronic equipment can be determined. Figure 3 is an example
of an electronic schematic diagram.
A second type of electronic schematic diagram, the pictorial layout diagram, is actually not so
much an electronic schematic as a pictorial of how the electronic circuit actually looks. These
drawings show the actual layout of the components on the circuit board. This provides a
two-dimensional drawing, usually looking down from the top, detailing the components in their
location. Shown in Figure 4 is the schematic for a circuit and the same circuit drawn in pictorial
or layout format for comparison. Normally the pictorial layout would be accompanied by a parts
list.
