NOTES: 10. Exceeds the AC‘97 specifications. Specified as the ratio of the rms output level with 1-kHz full-scale input
to the rms output level with all zeros into the digital input. Measured Awtd over a 20-Hz to 20-kHz bandwidth
(AES17–1991 idle channel noise or EIAJ CP–307 signal-to-noise ratio).
11. Measured using Awtd noise curve.
