AS IEC 61260.1:2019 PDF
The objective of this Standard is to specify performance requirements for analogue, sampled-data, and digital implementations of band-pass filters.
The objective of this Standard is to specify 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.
Performance requirements are provided for two filter classes: class 1 and class 2. In general, specifications for class 1 and class 2 filters have the same design goals and differ mainly in the acceptance limits and the range of operational temperature.
Band-pass filters conforming to the performance requirements of this Standard may be part of various measurement systems or may be an integral component of a specific instrument such as a spectrum analyser.
This Standard is identical with, and has been reproduced from, IEC 61260-1:2014, Electroacoustics — Octave-band and fractional-octave-band filters — Part 1: Specifications.
