Description

The purpose of this American National Standard Specification for Octave-Band and Fractional-Octave-Band Analog and Digital Filters is to specify the geometric mean frequencies, bandedge frequencies, band-widths, attenuation characteristics, bandwidth error, and other pertinent design parameters for constant-percentage-bandwidth bandpass filters so that spectral analyses made with filters conforming to the specified performance requirements will be consistent within known tolerance limits.

Scope

The scope of this standard specification includes bandpass filter sets suitable for analyzing electrical signals as a function of frequency. The bandwidth of the filters is a constant percentage of the midband frequency of each filter band. The scope includes passive, active, and sampled-data bandpass filters obtained by any design realization procedure. All filters, including fractional-octave-band filters synthesized by Discrete Fourier Transform (FFT) techniques shall meet all electrical requirements of the standard. Three frequency ranges of filter sets are described for use in the audio-frequency range where the reference frequency is one kilohertz. The filters in a filter set may be of any filter design Order. Four filter Types and five Sub-Types are established based on the amount of passband ripple and on the bandwidth error for both white noise and random noise having specified moderately sloping spectral distributions.
