Abstract:
These test procedures are to bring up to date the IRE "Standards on Facsimile-Temporary Test Standards-1943" (43 IRE 9.S1). In part there has been new experience and technological advance since then. But it has also been noted that that document could, to advantage, be made more complete and cover a wider range of tests. An important objective has therefore been to make the new test procedures more comprehensive, to cover tests for determining most of the measurable quantities that were defined in IRE Standards on Facsimile: Definitions of Terms (56 IRE 9.S1, ASA C16.30-1957) now IEEE No. 168. The scope, in part, has been derived from facsimile equipment des...
Scope:
Facsimile is defined as the process, or the result of the process, b y which fixed graphic material including pictures or images is scanned and the information converted into signal waves which are used either locally or remotely to produce, in record form, a likeness (facsimile) of the subject copy.
Purpose:
The purpose of this Test Procedure is to specify uniform methods of measuring performance characteristics of facsimile systems. Underlying theory is generally omitted as this material is available from other sources, but a brief discussion is given of the principles involved for each measurement. Where possible the measurements call for the use of the IEEE Facsimile Test Chart, which provides a convenient high-quality testing tool. The CCITT has also developed a test chart which is in use in many countries throughout the world. The general measuring procedures are outlined here and the factors which affect the accuracy of the results are discussed along with...
