AEC
Acoustic Echo Cancellation
A type of signal processing commonly used in teleconferencing. The
speech from the far-end caller is broadcast by the speakerphone or the
hands-free cellular phone and then repeats itself by bouncing off the
inside surfaces of a room or car. This repetition of sound is called an
echo. Echoes are picked up by the near-end microphone, creating a
feedback loop where the far-end caller hears an echo of his or her
own voice. AEC is developed to solve this problem.
AGC
Automatic Gain Control
A process or means by which gain is automatically adjusted in a
specified manner as a function of a specified parameter, such as
received signal level.
