Claims (1)

음성기록 및 재생장치에 있어서, 시스템을 제어하며, 정상재생 동작시 제1제어신호를 발생하고 리피트신호 발생시 제2제어신호를 발생하는 마이컴과, 상기 마이컴의 어드레싱 및 제1제어신호에 의해 소정 디지탈 음성데이타가 저장되고, 어드레싱 및 제2제어신호에 의해 해당번지에 저장한 음성데이타가 리드되는 메모리와, 헤드에서 재생한 음성신호를 입력하며 상기 마이컴의 제1제어신호에 의해 인에이블되어 음성신호를 상기 디지탈 음성데이타로 변환출력하는 A/D변환기와, 상기 마이컴의 제2제어신호에 의해 인에이블되어 메모리에서 리드된 음성데이타를 아날로그변환하는 D/A변환기와, 상기 D/A변환기의 출력을 저역여파하는 저역필터와, 상기 리프트신호의 발생여부에 따라 헤드를 통한 음성신호 또는 상기 저역필터를 통한 음성신호를 선택 출력하는 스위칭 수단으로 구성됨을 특징으로 하는 메모리를 이용한 음성기록장치.An audio recording and reproducing apparatus, comprising: a microcomputer that controls a system, generates a first control signal during a normal playback operation, and generates a second control signal when a repeat signal is generated, and a predetermined digital signal based on the addressing and the first control signal of the microcomputer. The voice data is stored, and the memory data to which the voice data stored at the corresponding address is read by the addressing and the second control signal is input, and the voice signal reproduced by the head is input and is enabled by the first control signal of the microcomputer. An A / D converter for converting and outputting the digital voice data into the digital voice data, a D / A converter for analog-converting voice data read from a memory enabled by a second control signal of the microcomputer, and an output of the D / A converter. A low pass filter for low pass filtering and a voice signal through the head or a voice signal through the low pass filter according to whether the lift signal is generated Voice recording apparatus using a memory, characterized in that consisting of a switching means for outputting. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
