徒弟:在前一节,师傅讲述的“逐次渐近比较式电压/数字转换器电路”(图48)之中,有“数/模转换器”、“移位寄存器”和“存储寄存器”,请师傅补充讲一讲它们的概念(名词术语)及作用好吗? 师傅:数/模转换器就是数字/模拟(D/A)变换器,即二进制数字电平信号变换成等效的模拟电压的过程,它是A/D(模/数)变换的逆变换。在图48中“数/模转换器”的作用是产生与输入电压各位数相对应的输出电压,例如:当“数/模变换器”输入端最高位有“1”(高电平)输入时,其输出端将产生模拟输出电压
Apprentice: “D / A Converter”, “Shift Register” and “Memory Register” in the “Asymptotic Comparable Voltage / Digital Converter Circuit” (Figure 48) Master please add to talk about their concepts (terminology) and the role of good? Master: D / A converter is the digital / analog (D / A) converter, that is, the binary digital signal into the equivalent analog voltage The process, which is the A / D (A / D) transform the inverse transform. In Figure 48, the “D / A converter” is used to generate the output voltage corresponding to each digit of the input voltage. For example, when the highest bit of the D / A converter has a “1” (high) input , Its output will produce analog output voltage
