Functional schematic diagrams

A carefully planned schematic diagram will simplify the study and servicing of electronic equipment. Whereas a conventional schematic merely shows the electrical components and how they are connected, a functional schematic will place these parts on the drawing in such a way as to delineate the circuits they build. This circuit concept versus component concept is the main thesis of this paper. It is expanded by considering major equipments as electrical structures built of circuits, and by treating components as having functions to perform in their circuits. These points are illustrated with functional drawings. Ideas and techniques are suggested which can make schematic diagrams more lucid.
