Electroacoustics - Octave-band and Fractional-octave-band Filters - Part 1: Specifications
This standard provides performance requirements for analog, sampled-data, and digital implementations of band-pass filters that comprise a filter set or spectrum analyzer for acoustical measurements. It supersedes ANSI/ASA S1.11-2004 (R2009) American National Standard Specification for Octave-Band and Fractional-Octave-Band Analog and Digital Filters, and is an identical national adoption of IEC 61260:2014 Electroacoustics – Octave-band and fractional-octave-band filters, Part 1: Specifications. Significant changes from previous versions is that IEC 61260 has been adopted in full: (1) the original test methods of IEC 61260 clause 5 that was moved to an informative annex was replaced as normative, (2)the term “band number,” was replaced, and (3) some references were removed.
