Automatic gain control module, method for controlling the same, vehicle including the automatic gain control module, and method for controlling the vehicle

摘要

An automatic gain control module includes a first operation unit for determining a first gain value used for amplification of a voice signal in a manner that an energy of the voice signal received from an external part reaches a target energy, a second operation unit for determining a second gain value used for amplification of the voice signal in a manner that a peak value of the voice signal reaches a maximum value capable of being amplified, and a voice amplification unit for amplifying the voice signal according to a minimum value from among the first gain value and the second gain value.
