Claims (1)

  1. 디지탈 형태로 얻을 수 있는 오디오 신호의 소정 주파수 대역 위치하는 주파수 성분의 위상 및 진폭을 제어하기 위한 장치로서, 디지탈 오디오 신호가 공급되며, 또한 기억수단에 기억된 필터 계수를 수신하도록된 순환부분과 비순환 부분을 가진 순환 디지탈 필터를 구비하고 있는 디지탈 톤 제어장치에 있어서, 기억수단은 필터계수의 한 단일 제1 부분군만을 기억시키기 위한 제1 기억장과 각 필터계수의 제2 부분군이 기억되는 다수의 제2 기억장으로 분할되며, 제1 기억장에 기억된 필터계수의 제1 부분군을 비순환 부분이나 또는 순환부분중의 한곳에 공급하고 또한 필터계수의 제2 부분군을 필터계수의 제1 부분군이 공급되지 않은 비순환 부분과 순환부분에 공급하는 수단이 설치되어 있는 것을 특징으로 하는 디지탈 톤 제어장치.
