This standard contains graphic symbols for representing logic functions or physical devices capable of carrying out logic functions. Descriptions of logic functions, the graphic representation of these functions, and examples of their applications are given. The symbols are represented in the context of electrical applications, but most may also be applied to nonelectrical systems (for example, pneumatic, hydraulic, or mechanical).

This standard provides a set of letter symbols for quantities and abbreviations and recommendations for their use in the science and technology of acoustics. The science and technology of acoustics includes sound, ultrasound, and infrasound in all media. Gases, especially air; liquids, especially water; and solids are examples of media with which acoustics is concerned. Specialties within acoustics that make use of the letter symbols and abbreviations within this standard include, but are not… read more limited to: speech, hearing, music, noise control, vibration, shock, sonar, and transducers. Although remarks and limited short-form information are provided for many of the symbols and abbreviations contained herein, definitions and methods of calculating the various quantities are outside the scope of this standard. read less

The IEEE Standards Coordinating Committee for Letter and Graphic Symbols recognizes the need for guidelines to be used in developing and applying those symbols that are employed in the electrical and electronics fields. These include: abbreviations, functional designations, graphic symbols, letter combinations, mathematical symbols,reference designations, symbols for quantities, and symbols for units. Such guidelines are useful not only to members of the Standards Coordinating Committee, but are especially helpful to any other committee engaged in developing Standards Publications in the areas mentioned. Accordingly, these guidelines have been formulated and are given in detail herein.

Only signs and symbols used in writing mathematical text are contained in this Standard. Special symbols peculiar to certain branches of mathematics, such as non-Euclidean Geometries, Abstract Algebras, Topology, and Mathematics of Finance, which are not ordinarily applied to the physical sciences and engineering, have been omitted. Because there is no consensus in the literature for signs and symbols used in tensor analysis, the subject of tensors is relegated to future editions when there is… read more general agreement among authorities in the field. read less
