디지탈신호 기록/재생 장치Digital signal recording / playback device

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 따른 디지탈신호 기록/재생 장치의 블럭도.1 is a block diagram of a digital signal recording / reproducing apparatus according to the present invention.

Claims (1)

디지탈신호 기록/재생 장치에 있어서, 디지탈신호 입력단자(13), 디지탈/아나로그 선택 입력단자(14), 기록/재생신호 입력단자(16), 아나로그 신호 입력단자(18)와, 소정 제어에 의해 디지탈 신호를 기록하고 기록된 디지탈신호를 재생신호로 출력하는 DSM(20)과, 디지탈 변조된 디지탈신호를 바이페이즈(Bi-phase) 복조하여 PCM 데이터로 출력하는 바이페이즈 복조기(22)와, 디지탈 신호를 아나로그신호로 변환하여 모니터링신호로서 출력하는 DAC(24)와, 상기 DAC(24)의 출력과 상기 아나로그신호 입력단자(18)의 입력신호를 입력하여 상기 디지탈/아나로그 선택신호 입력단자(14)의 입력신호에 의해 스위칭되어 두 신호중의 하나를 선택출력하는 아나로그스위치(26)와, 상기 아나로그스위치(26)의 출력을 디지탈 변환하여 출력하는 ADC(28)와 상기ADC(28)로 부터 출력되는 디지탈신호를 처리하여 상기 DSM(20)에 기록하고, 상기 DSM(20)에서 재생되는 신호를 신호처리하여 외부의 디지탈 신호로 출력함과 동시에 재생 PCM 데이타를 출력하는 DSP(30)와, 상기 바이페이즈 복조기(22)의 출력과 상기 ADC(28)의 출력을 상기 디지탈/아나로그 선택 신호단자(14)의 입력신호에 따라 선택출력하는 제1멀티플렉서(32)와, 상기 제1멀티플렉서(32)의 출려과 DSP(30)의 재생 PCM 데이터를 입력하며, 상기 기록/재생신호 입력단자(16)의 신호입력에 따라 두신호의 입력중 하나의 신호를 상기 DAC(24)로 제공하는 제2멀티플렉서(34)로 구성함을 특징으로 하는 장치.In the digital signal recording / reproducing apparatus, the digital signal input terminal 13, the digital / analog selection input terminal 14, the recording / reproducing signal input terminal 16, the analog signal input terminal 18, and predetermined control A digital signal and a digital phase demodulator 22 for bi-phase demodulating and outputting the digitally modulated digital signal as PCM data; Selects the digital / analog signal by inputting a DAC 24 that converts a digital signal into an analog signal and outputs it as a monitoring signal; and an input signal of the output of the DAC 24 and the analog signal input terminal 18. An analog switch 26 which is switched by an input signal of the signal input terminal 14 to selectively output one of the two signals, and an ADC 28 which digitally converts and outputs the output of the analog switch 26; Dee output from ADC 28 A DSP 30 for processing a digital signal and recording the signal to the DSM 20, processing the signal reproduced by the DSM 20, outputting it as an external digital signal, and simultaneously outputting reproduction PCM data; A first multiplexer 32 for selectively outputting the output of the phase demodulator 22 and the output of the ADC 28 according to the input signal of the digital / analog selection signal terminal 14, and the first multiplexer 32; And a second multiplexer for inputting the reproduction PCM data of the DSP 30 and providing one of the two signals input to the DAC 24 according to the signal input of the recording / reproducing signal input terminal 16. Apparatus characterized by consisting of (34). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
