## Scales and sizes for plotting frequency characteristics and polar diagrams

active, Most Current
 Organization: IEC Publication Date: 1 June 2020 Status: active Page Count: 32 ICS Code (Electroacoustics): 17.140.50
##### scope:

This document specifies standard aspect ratios for logarithmic or level characteristics expressed in decibels versus a logarithmic frequency axis and ranges for the radius of polar diagrams of level. Applications include hard copy printouts, electronic files (e.g., PDF files), scientific publications, screen displays in computer programs and apps, as well as graphs in standards.

Informative examples of graphs that conform to the requirements in this document are found in Annex A.

Although outside the scope of this document, graphs with a linear y-axis versus logarithmic frequency (e.g., phase, group delay, etc.) often accompany the standard aspect ratio graphs of level described in the normative part of this document. These are described in informative Annex B.
