ASA S1.11-2014/Part 1 / IEC 61260:1-2014 (R2019)
American National Standard for Electroacoustics - Octave-band and Fractional-octave-band Filters - Part 1: Specifications (a nationally adopted international standard)
standard by American National Standards of the Acoustical Society of America, 07/02/2014
Full Description
This part of the ANSI/ASA S1.11 / IEC 61260 series specifies performance requirements for analogue, sampled-data, and digital implementations of band-pass filters. The extent of the pass-band region of a filter's relative attenuation characteristic is a constant percentage of the exact mid-band frequency for all filters of a given bandwidth. An instrument conforming to the requirements of this standard may contain any number of contiguous band-pass filters covering any desired frequency range.
