BS EN 61606:1997- Audio and audiovisual equipment. Digital audio parts. Basic methods of measurement of audio characteristics

Description Printed version of this is available at library. To request, please e-mail to referencepk@usm.my and include a copy of this record in your e-mail. Abstract This International Standard is applicable to the basic methods of measurement of the audio characteristics of the digital audio part of audio and audiovisual equipment (for both consumer and professional uses). The common measuring conditions and methods are described, which are used in the measurement of performance characteristics of equipment having an audio bandwidth approximately one-half of the sampling frequency of a system, where the audio information is processed in the form of digital data. CD players, DAT recorders, digital amplifiers, digital sound broadcast receivers and television broadcast receivers with digital sound are some of the examples. Methods specified in this standard are not applicable to systems incorporating bit-rate reduced digital audio signals. This standard only describes tests for equipment with analogue output and digital input. Future revision of this standard will cover digital in/digital out, analogue in/digital out and analogue in/analogue out tests.
