Schematic diagrams

Look back through the earlier chapters of this book and observe the schematic dia-
grams. These are all simple examples of how professionals would draw the circuits.
There is no inscrutable gobbledygook to put in to make them into the sorts of circuit
maps that the most brilliant engineer would need. The diagrams you have worked with
are exactly like the ones that the engineer would use to depict these circuits.
