Parameter Name
Table 2-4: TUNABLE PARAMETERS: Software Automatic Gain Control
Determines the desired time scale for SWAGC algorithm operation.
Increasing this parameter decreases the time scale, and the
SWAGC reacts quicker to changes in input levels and can become
more sensitive to fluctuations in signal power. Default value is
equivalent to 5 sec per 12dB change.
Different values of the tunable parameter can be used for the
compression and Speakerphone algorithms. In order to change
the value of the tunable parameter use the TUNE command prior
to entering each of the two algorithms.
Legal values: 0 - 32767
Low bound of desired signal power. The SWAGC algorithm
amplifies the gain whenever the output signal power decreases
below AGC_POWER_LOW.
The default value is equivalent to
Each multiplication of the value by 2 adds approximately 3dB to
the output power.
Different values of the tunable parameter can be used for the
compression and Speakerphone algorithms. In order to change
the value of the tunable parameter use the TUNE command prior
to entering each of the two algorithms.
Legal values: 0 - 32767
High bound of desired signal power. The SWAGC algorithm
attenuates the gain whenever the output signal power increases
above AGC_POWER_HIGH.
The default value is equivalent to
Each multiplication of the value by 2 adds approximately 3dB to
the output power.
Different values of the tunable parameter can be used for the
compression and Speakerphone algorithms. In order to change
the value of the tunable parameter use the TUNE command prior
to entering each of the two algorithms.
Required value for speakerphone mode is 5000. This value should
be given only if the SWAGC is enabled in this mode.
Legal values: 0 - 16384
This tunable parameter controls the maximum gain of the SWAGC
algorithm. Adding 1 to the tunable parameter increases the gain
by 6dB.
Default is equivalent to 12dB gain.
Different values of the tunable parameter can be used for the
compression and Speakerphone algorithms. In order to change
the value of the tunable parameter use the TUNE command prior
to entering each of the two algorithms.
