现在最常用的是比较型转换器,它的趋势是线路固体化和要求特高的精度和速度。下面介绍几种较新的线路:1.用晶体管线路的转换器这里可用N.Witerbottom 提出的模拟-数字转换器作为代表,它的指标如下:内部标准脉冲频率为500千周;整量化速度最大为每秒55;000次采样;输入信号从零到六伏;输入阻抗1.5千欧;输出为8个二进位;工作温度范围0°～40°G,精度±0.25%。在这个变换器的比较器里用了两个特性匹配的高频微合金
The most common type of converter used today is the trend of solidifying circuits and requiring extremely high accuracy and speed. Here are a few of the newer lines: 1. Transistor Transistor Transceivers There is an analog-to-digital converter represented by N. Witerbottom, whose specifications are as follows: internal standard pulse frequency of 500 kilo-cycles; maximum integer quantization speed 55,000 samples per second; input signal from zero to six volts; input impedance of 1.5 kilohms; output of 8 binary; operating temperature range of 0 ° ~ 40 ° G, accuracy of ± 0.25%. Two matched high-frequency micro-alloys were used in the converter’s comparator
