Abstract

본 발명은 디지탈 음량 조절장치를 공개한다. 그 장치는 입력되는 신호의 0점을 검출하기 위한 0점 검출수단, 입력되는 신호를 소정 전압 분배하여 분배된 전압을 출력하기 위한 볼륨 저항 어레이 수단, 상기 0점 검출수단의 출력신호에 응답하여 상기 볼륨 저항 어레이 수단을 제어하기 위한 볼륨 저항 어레이 제어수단으로 구성되어 있다. 따라서, 고주파수의 신호성분을 제거하고 정확한 출력신호를 발생할 수가 있게 된다.The present invention discloses a digital volume control device. The apparatus comprises zero point detection means for detecting zero point of the input signal, volume resistor array means for outputting a divided voltage by dividing the input signal by a predetermined voltage, and in response to the output signal of the zero point detection means. And a volume resistance array control means for controlling the volume resistance array means. Therefore, it is possible to remove a high frequency signal component and generate an accurate output signal.
