TS 4829

TS 4829 is a terminology standard that gathers terms and definitions for analog computing. Read together, the title and scope show that it organises concepts related to analog and hybrid arithmetic units, function generators, converters, and the operating modes of such components. As a vocabulary standard, its value lies in keeping technical language consistent across languages and institutions.

How analog and hybrid computing concepts fit together

Analog computing uses continuously varying physical quantities rather than discrete numerical symbols to represent variables. Voltage, current, mechanical motion, or similar quantities may stand for a value, so arithmetic functions, conversion, and function generation are carried out by dedicated devices and circuits. Hybrid arithmetic systems combine analog and digital approaches within one arrangement. That distinction matters because it shapes how the equipment is described, how functions are interpreted, and how related terms are used.

The conceptual area covered by this vocabulary

• Names for analog and hybrid arithmetic units
• Terms connected with function generators and their role
• Concepts associated with converters and conversion processes
• Expressions for modes of operation of these components
• Consistent technical wording for international communication

This document is best understood as a controlled vocabulary source rather than a method or performance-test standard. Its equivalence to ISO 2382-19:1980 places it within the information processing terminology family. Although analog and hybrid computing are now most often encountered in historical, specialist, or niche contexts, the terminology remains useful for understanding measurement, modelling, control, and early information-processing systems.
