Overview
IEC 60050-702:1992/AMD3:2017 is the third amendment to Part 702 of the International Electrotechnical Vocabulary (IEV), focusing on oscillations, signals, and related devices. Published by the International Electrotechnical Commission (IEC), this amendment updates and refines terminology critical to the fields of telecommunications, signal processing, and electronic oscillations. It forms part of the global IEC standards that ensure consistency and clarity in electrotechnical language, serving as an authoritative reference for engineers, researchers, and industry professionals.
This amendment revises important definitions related to frequency spectra, bandwidth, radio frequencies, signal quantization, and modulation techniques, helping standardize electrotechnical vocabulary across international markets. The updated terms also align with recent developments and harmonize with other international standards bodies.
Key Topics
Frequency Spectrum in Telecommunication
Defines the range of frequencies of oscillations or electromagnetic waves used for information transmission, essential for communication system design and spectrum management.Bandwidth
Clarified definitions of frequency bandwidth and device bandwidth, key concepts in analyzing signal transmission capability and device performance.Radio Frequency (RF)
Specifies the frequencies associated with radio waves and electric oscillations, highlighting the term’s application to devices generating or detecting radiated waves.Root-Power Quantity
Introduces quantities whose squares are proportional to power, relevant in signal and field measurement.Phase and Group Delay
Defines the propagation times of wavefronts and signal groups between points along transmission paths, vital for understanding signal distortion and timing.Envelope Delay
Explains delay concepts related to significant spectral components assuming minimal distortion, critical in signal integrity evaluation.Discrete Signals and Quantization
Describes signals composed of discrete elements and the process of mapping continuous values into predetermined ranges, foundational in digital communications and signal processing.Time Scales and Cyclic Timescale
Details periodic repetition of time intervals or cycles used in signal framing and synchronization.Digits and Digit Rate
Covers representations of information using integers within finite sets and their transmission speed - the digit rate - crucial for digital transmission systems.Differential Modulation and Modulation Techniques
Defines modulation methods where information is conveyed through changes relative to preceding signal elements, including differential phase shift keying (DPSK), important in digital communication modulation schemes.
Applications
IEC 60050-702:1992/AMD3:2017 serves as a fundamental resource across various industries and applications, including but not limited to:
Telecommunications Engineering
Engineers designing and maintaining communication systems rely on clear terminology for frequency spectrum allocation, modulation protocols, and signal timing to optimize transmission quality and interoperability.Signal Processing
Clarifications on discrete signals, quantization, and envelope delay enable more precise algorithm development for digital signal encoding, decoding, and analysis.Radio Frequency Equipment Design
Manufacturers of RF devices and systems utilize standardized definitions for frequency bands and modulation techniques to ensure compliance with international regulations and compatibility.Measurement and Testing
Accurate use of terms like group delay and root-power quantities supports precise characterization of oscillations and signals in metrology laboratories.Standardization and Compliance
By adopting consistent electrotechnical vocabulary, regulatory bodies and standard developers streamline cross-border certification and communication.

Note 1 to entry: In a homogeneous medium, or on a uniform transmission line, the group delay is equal to the
derivative with respect to the angular frequency of the difference, at the same time, of the phases, at the two
points, of the signal used to define the group velocity.
Note 2 to entry: In practice, if the medium is not too absorbent, nor too anisotropic, nor too dispersive, the group
delay is equal to the propagation duration of the signal used to define the group velocity.
