A Note From
the EDITOR

Our November editor’s note talked about analog design as an art form. That notion seemed to resonate (pardon the engineering pun) with quite a few of our readers out there. Jack Memishian, Analog Devices Fellow (1980), sent me an email...

The Schematic Diagram: A Basic Element of Circuit Design

There seems to be a limitless amount of information that can be learned in the field of electrical engineering. One of the most essential skills for an electrical engineer is the ability to read and create schematics. Before you start learning Ohm’s law, superposition theorem, and delta-wye transforms, you need a basic understanding of how to read (and draw) a circuit schematic.

I like the definition of schematic in Wikipedia: “A schematic, or schematic diagram, is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the information the schematic is intended to convey, and may add unrealistic elements that aid comprehension … In an electronic circuit diagram, the layout of the symbols may not resemble the layout in the circuit.”  Read more ...
