ABSTRACT:
A gain controller for use in mobile telephone system is disclosed. It is judged whether digital input data includes speech data or not. When the digital input data includes speech data, an integration energy value of the digital speech data for a predetermined time length is measured. The measured integration energy value is compared with a higher threshold value and a lower threshold value. A step level is set to a predetermined minus value, a predetermined plus value and "0" when the integration energy value is higher than the higher threshold value, lower than the lower threshold value and within a range between the higher and lower threshold values, respectively. The obtained step level is then added to the digital speech data.
