Abstract

본 발명은 다이나믹 이퀼라이져에 관한 것으로, 종래에는 방송모드에 따라 음성신호의 특성을 살리기 위해서는 사용자가 직접 키를 조작하여 방송모드를 선택해야 함은 물론이고 임의의 방송모드를 선택하더라도 선택된 방송모드가 특정 대역의 주파수만이 지속적으로 출력되지 않으므로 상황에 따라 각 주파수 대역의 음성신호가 합성되어 방송모드의 특성을 살리지 못하는 경우가 있었다. 이에 본 발명은 R 채널과 L 채널의 음성신호를 완충하는 버퍼와, 상기 R 채널의 음성신호와 L 채널의 음성신호를 합성하는 합성부와, 다수개의 밴드 패스필터로 구성되며 상기 밴드 패스 필터를 통한 음성신호를 디지탈 신호로 변환하는 밴드 이퀄라이져 검파부와, 상기 각 밴드별 음성신호의 레벨을 검출하여 방송모드를 판단하고 이에 해당하는 대역의 음성신호를 증폭하기 위한 데이터를 출력하는 마이크도 프로세서를 구성함으로써 보다 현장감있는 음성신호를 제공할 수 있는 것이다.The present invention relates to a dynamic equalizer. In the past, in order to utilize the characteristics of a voice signal according to a broadcast mode, a user must directly select a broadcast mode by operating a key, Since only the frequency of the band is not continuously outputted, the voice signal of each frequency band is synthesized depending on the situation, and the characteristics of the broadcasting mode can not be utilized in some cases. According to an aspect of the present invention, there is provided a radio communication system including a buffer for buffering R-channel and L-channel audio signals, a synthesizer for synthesizing the R-channel audio signal and the L-channel audio signal, And a microphone processor for outputting data for amplifying a voice signal of a corresponding band by detecting a level of a voice signal for each band and determining a broadcasting mode, It is possible to provide a more realistic voice signal.
