Overview
The IEC 60050-702:1992/AMD2:2016 is an important amendment to the International Electrotechnical Vocabulary (IEV), specifically Part 702, which covers Oscillations, Signals, and Related Devices. Published by the International Electrotechnical Commission (IEC), this amendment updates the terminology and definitions used globally in the fields of electrical and electronic engineering.
This standard provides precise, internationally accepted definitions of key terms related to oscillations, signal processing, modulation, coding, and related devices. The vocabulary ensures uniform understanding and communication across industries and research disciplines involved with electrotechnical technologies.
Key Topics
IEC 60050-702:2016 Amendment 2 addresses the following critical concepts:
- Baseband: Defines the frequency band occupied by one or more multiplexed signals in a transmission system, critical for understanding transmission and modulation stages.
- Absorption: Describes the conversion of electromagnetic or acoustic wave energy into other forms, such as heat, when interacting with matter.
- Analogue Signal: A signal with continuously variable values representing information, fundamental in electronic communication systems.
- Automatic Gain Control (AGC): Mechanism used to maintain consistent output signal levels despite variable input amplitudes, widely applied in amplifiers and receivers.
- Binary Digit (Bit): The fundamental unit of digital information, consisting of two possible states, essential in digital communication and data processing.
- Byte: An ordered set of eight binary digits operated as a unit, forming the basis of digital information storage and processing.
- Code Conversion (Transcoding): Changing information representation from one code system to another, important in data communications and telegraphy.
- Redundant Codes: Codes containing extra signal elements beyond the minimum necessary for data representation, enabling error detection and correction.
- Error Detecting and Correcting Codes: Specialized redundant codes designed to automatically detect and correct errors in the transmission or processing of information.
- Modulation and Carrier: Definitions related to oscillations used in transmitting information by varying carriers with signals, including amplitude modulation (AM) and amplitude shift keying (ASK).
- Baud: The unit of modulation rate or line digit rate, critical in measuring data transmission speed.
This amendment refines definitions and replaces outdated terms to enhance clarity and standardization.
Applications
The vocabulary outlined in IEC 60050-702:2016 Amendment 2 is essential for a broad spectrum of practical applications, including:
- Telecommunication Systems: Understanding and designing signal modulation, coding, and transmission based on standardized terminology.
- Electronics Manufacturing: Developing devices such as amplifiers, modulators, and signal processors that rely heavily on standardized electrotechnical vocabularies for quality and compliance.
- Digital Communications: Employing error detecting and correcting codes to ensure data integrity in networks and digital broadcasting.
- Signal Processing: Applying concepts like automatic gain control and analogue/digital signal interpretation for audio, video, and sensor technologies.
- Education and Research: Providing a reliable knowledge base for students, educators, and researchers working in fields related to electrical engineering and communications technology.
By adhering to the IEC vocabulary, professionals ensure interoperability, reduce ambiguities, and facilitate international collaboration.
Related Standards
IEC 60050-702:2016 links closely with other international standards that collectively support electrotechnical terminology and practices:
- IEC 60050 (General Electrotechnical Vocabulary): Covers broad electrical and electronic terms beyond oscillations and signals.
- IEC 701 Series (Modulation Vocabulary): Provides detailed terminology on modulation techniques referenced in this amendment.
- IEC 721 and IEC 721-03 (Telegraphy and Digital Data Codes): Related to terms defining digital codes, error detection, and correction used in communication standards.
- Various IEC TC 1 Terminology Projects: Ongoing efforts to maintain and update electrotechnical terms online via Electropedia (www.electropedia.org).
- CISPR Publications: Some entries related to radio communication and signal standards overlap with work by CISPR, the specialized IEC committee for radio interference.
For the latest terminology and definitions, users are encouraged to consult the online IEC Electropedia and verify the edition and amendments of standards, as the IEC maintains continuous updates.
By aligning with IEC 60050-702:2016 Amendment 2, industries and academia gain access to the most accurate and current international electrotechnical vocabulary related to oscillations, signals, and related devices-enhancing communication, efficiency, and innovation in the global electrotechnical landscape.

baseband
frequency band occupied by one signal or by a number of multiplexed signals at specified
input and output points of a transmission system
Note 1 to entry: In radiocommunication, the baseband is that frequency band occupied by the signal modulating the
radio transmitter.
Note 2 to entry: When the transmission involves multiple modulation, it is generally considered that the baseband
is that frequency band occupied by the signal which is applied to the first modulation stage, and not the frequency
band occupied by an intermediate modulated signal.
bande de base, f
bande de fréquences occupée par un signal, ou par un ensemble de signaux multiplexés, en
des points spécifiés à l'entrée et à la sortie d'un système de transmission

signal qui module l'émetteur radioélectrique.
Note 2 à l'article: Dans une transmission comportant une modulation multiple, on considère généralement comme
bande de base la bande de fréquences occupée par le signal appliqué au premier étage de modulation et non la
bande de fréquences occupée par un modulat intermédiaire.
