AGC 19
Automatic Gain Control Attack
Time: The time constant of the RC
network connected to this input
determines the AGC attack time.
The attack time is defined as the
delay present before the AGC
circuit begins to adjust gain. The
values shown in the reference
schematics have been optimized
for voice Applications.
