【摘要】 介绍最新研制成功并投入使用的电化教学仪器。它采用数据编码、调制和解调技术，将语音信息和相应的文字图象信息处理成语音形式录制在普通录音磁带上，声象同步器在播放磁带时，同步输出音频的语音信息和视频的图象信息，达到视听结合的教学效果。当暂停播放磁带时，能重复播放上一段的语音信号。与计算机结合使用，能编辑制作声象教材。更多还原

【Abstract】 novel audio-video synchronizing education equipment has been developed and used successfully. With data coding, modulating and demodulating techniques, the audio information and the corresponding text pattern information are processed and converted to some kind of audio signal and recorded on the common magnetic tapes. When the tape is playing,the synchronizer outputs the audio signal and the visible text simultaneously, and a reading-listening combined education is successfully achieved. When the "Pause"button is depressed,the last segment of the audio signal (or sentence) will be repeated automatically until the "Pause"button is released. Connected with a microcomputer,audio-video teaching materials can be edited and produced on this equipment.更多还原
