Claims (3)
- 오디오데이타기록디스크로부터 오디오데이타를 재생하기 위한 디스크플레이어에 있어서, 상기 디스크를 회전시키기 위한 모터, 재생음의 빠르기를 선택하는 명령을 입력하기 위한 키입력부; 상기 키입력부의 재생음빠르기선택명령에 따라 시스템클럭발생회로와 PLL회로의 주파수를 가변시키기 위한 제어부; 상기 제어부에 의해 가변하는 메인클럭과 PLL의 주파수를 DSP로 공급하기 위한 시스템클럭발생회로와 PLL회로; 및 상기 가변하는 주파수에 따라 디스크로부터 독출되는 오디오데이타를 처리하고, 상기 모터의 회전속력을 제어하는 DSP를 포함하는 여러가지 빠르기로 오디오신호를 재생하는 디스크플레이어.
- 제1항에 있어서, 상기 제어부에 연결되며, 재생음의 빠르기상태를 알려주기 위한 표시부를 더 포함하는 여러가지 빠르기로 오디오신호를 재생하는 디스크플레이어.
- 제1항 또는 제2항에 있어서, 상기 DSP는 상기 시스템클럭발생회로로부터 공급받은 메인클럭과 상기 PLL회로로부터 공급받은 PLL중심주파수가 일치하도록 PLL회로를 제어하는 것을 특징으로 하는 여러가지 빠르기로 오디오신호를 재생하는 디스크플레이어.
