Abstract
본 발명은 입력되는 음성신호의 레벨업 현상으로 인해 음성신호가 영상신호에 미치는 간섭을 방지할 수 있도록 한 고주파신호 변조장치에 관한 것으로, 입력되는 음성신호에 대해 특정주파수 대역을 강조하기에 앞서 그 레벨을 설정된 소정레벨, 즉 허용 입력레벨로 자동 조절하기 위한 자동 레벨제어수단을 구비함으로써, 음성신호가 영상신호에 미치는 간섭이 배제되어 화질열화가 방지되도록 한 것이다.The present invention relates to a high frequency signal modulation device that can prevent the interference of the audio signal to the video signal due to the level-up phenomenon of the input audio signal, prior to emphasizing a specific frequency band for the input audio signal. By providing automatic level control means for automatically adjusting the level to a predetermined predetermined level, that is, an allowable input level, interference of the audio signal to the video signal is eliminated to prevent deterioration of image quality.
