本模块专为DDZⅢ开方单元设计,使仪表组装简单、调试方便性能一致性好.外加少量元件即可组成开方器、开方积算器.1.原理框图 输入(V_i)→电平移动计算→开方运算→电平移动计算功放→输出(V_0)2.传递函数:V_0=2(Vi-1)~(1/2)+13.本模块带小信号切除,精度为±(0.1%～0.3%),尺寸:50mm×50mm,系统精度达到:输入电压≥1.09V时±0.5%输入电压<1.09V≥1.04V时±1%输入电压<1.04V时不计精度为合格
This module is designed for DDZ Ⅲ square unit design, so that the instrument assembly is simple, easy debugging performance consistency. Add a small amount of components can be composed of an open square, open square calculator .1 block diagram input (V_i) → level shift Calculation → Open-square calculation → Level-shift calculation → Output (V_0) 2. Transfer function: V_0 = 2 (Vi-1) ~ (1/2) +13. % ~ 0.3%), Size: 50mm × 50mm, the system accuracy reached: ± 0.5% when the input voltage ≥ 1.09V Input voltage <1.09V ≥ ± 1.04V ± 1% When the input voltage <1.04V Accuracy is not qualified
