美国电声学国家标准.倍频带和分数倍频带滤波器.第2部分:模式评估试验(国家采用的国际标准)
This part provides details of the tests necessary to verify conformance to all mandatory specifications
given in ANSI/ASA S1.11-2014/Part 1/IEC 61260-1:2014 for octave-band and fractional-octave-band
filters. Tests and test methods are applicable to class 1 and class 2 bandpass filters. The aim is to ensure
that all testing laboratories use consistent methods to perform pattern-evaluation tests.
