Claims (1)

디지탈 신호 처리 장치와 D/A변환기 사이에, 가산기와 계수부 및 기억부와 제어신호 발생기로 구성되어 있는 디지탈 필터를 구성시켜, 디지탈 필터내부에서 디 엠퍼시 작용을 하도록 하며, 디지탈 신호 처리 장치로부터 구분하여 출력한 엠퍼시스 되어 있는 신호와 엠퍼시스 되어 있지 않은 신호상태에 따라 계수값을 보내어 계수값을 변환시켜 필터의 특성을 결정짓도록 함을 특징으로 하는, 디지탈 필터를 사용하여 음질의 손상을 제거한 디 엠퍼시 회로.A digital filter comprising an adder, a counter, a memory, and a control signal generator is constructed between the digital signal processing device and the D / A converter so as to perform a de-emphasis action within the digital filter. The digital filter is used to determine the characteristics of the filter by converting the coefficient value according to the emphasized signal and the non-emphasized signal state outputted separately. Removed de-emphasis circuit. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
