Revision 1.11Prism Sound dScope Series III

Standard notch filter -

A band-reject filter with a Q between 1 and 5, for example the dScope's

band-reject filter at the '1/3 octave' setting.

Standard weighting filter -

A weighting filter with a response according to CCIR468, but

normalised to have unity gain at 2kHz, for example the dScope's 'CCIR468–2k' weighting filter.

Upper band-edge frequency

- The maximum frequency to be measured, which must be less

than the

folding frequency

of the

EUT

. In most cases, the upper band-edge frequency is 20kHz

unless this is restricted by the sample rate of the EUT. The dScope implementations of the AES17

tests always set the upper band-edge frequency to 20kHz.
