Figure 29.
VOX delay and sensitivity schematics
On pin 6, Rpeak and Cpeak integrate the rectified audio signal with a short time constant. This
filtered signal follows the audio amplitude.
Figure 30.
VOX integrator and monostable schematics
The self-adaptive VOX threshold is necessary because the ambient background noise
variation is slow compared to the voice or the music. On pin 28, RCOMP and CCOMP
integrate the amplitude to follow the background amplitude. Therefore, the comparator
switches when an audio signal appears over the background noise. Referring to Figure 2,
CCOMP will be typically a 100 nF capacitor and RCOMP will be determined depending on the
audio signal.
As soon as an audio signal is detected, the output of the monostable switches to "high" state
and enables both output buffers. The monostable output is pin 27 and is called VOX-MUTE.
