6.3.2. A2 Threshold

The threshold between Stereo/Bilingual and Mono

Identification for the A2 Standard has been made pro-

grammable according to the user’s preferences.

An internal hysteresis ensures robustness and stability.

6.3.3. Carrier-Mute Threshold

The Carrier-Mute threshold has been made program-

mable according to the users preferences. An internal

hysteresis ensures stable behavior.
