一种不需要采样保持电路和编码器电路,结构简单的行波型模数转报器在中国科学院物理所首次研制成功.它全部采用现有国产TTI逻辑器件.可供视频图象信号的模拟数字转换用.在1979年2月研制成功的原理性样机基础上于1979年9月又研制成功一台改进型的13.3MHz,七位满刻度0—2V的A/D. A kind of traveling wave analog-to-digital converter with simple structure, which is not needed for sample-and-hold circuit and encoder circuit, was first developed successfully by Institute of Physics, Chinese Academy of Sciences.It uses all the existing domestic TTI logic devices and can simulate the video signal Digital conversion with the successful development of the prototype in February 1979 on the basis of the prototype in September 1979 and the successful development of an improved 13.3MHz, seven full scale 0-2V A / D.
