Abstract
본 발명은 채널별 음성 출력 레벨 조정 방법 및 장치에 관한 것으로, 현재 방송국에 따라 음성 신호의 변조도가 각기 다르므로 복조후의 음성 신호의 스윙 폭이 다르게 된다. 따라서, 종래에는 일정한 증폭율을 가진 음성 증폭기를 사용하는 경우 음성 신호의 스윙폭이 다르게 되면 음량이 달라지게 되어 채널 변경시마다 음성 신호의 출력 레벨이 달라지는 문제점이 있었다. 이러한 문제점을 해결하기 위하여 본 발명은 채널별 변조도와 사용자의 음성 출력 레벨값을 연산하여 해당 채널의 변조도에 대해 음성 증폭율을 보상하므로써 채널 변경시에도 일정한 음성 출력 레벨을 유지하도록 창안한 것으로, 본 발명은 채널이 변경될 때마다 해당 채널의 변조도에 대해 음성 출력 레벨값을 조정하므로써 볼륨 레벨을 조정함이 없이 일정한 음성 출력 레벨을 얻을 수 있다.The present invention relates to a method and apparatus for adjusting the audio output level for each channel. Since the modulation degree of the audio signal varies depending on the current broadcasting station, the swing width of the audio signal after demodulation is different. Therefore, when a voice amplifier having a constant amplification rate is used in the related art, when the swing width of the voice signal is different, the volume is changed, and thus, the output level of the voice signal is changed at every channel change. In order to solve this problem, the present invention has been devised to maintain a constant voice output level even when a channel is changed by calculating a modulation rate for each channel and a voice output level value of the user to compensate for the amplification rate of the corresponding channel. The invention can obtain a constant voice output level without adjusting the volume level by adjusting the voice output level value with respect to the modulation degree of the corresponding channel whenever the channel is changed.
