Question

An Analogue to Digital Converter, (ADC from now on) is better known as a dual slope converter or integrating converter. This type of converter is generally preferred over other types as it offers accuracy, simplicity in design and a relative indifference to noise which makes it very reliable. The operation of the circuit is better understood if it is described in two stages. During the first stage and for a given period the input voltage is integrated, and in the output of the integrator at the end of this period, there is a voltage which is directly proportional to the input voltage. At the end of the preset period the integrator is fed with an internal reference voltage and the output of the circuit is gradually reduced until it reaches the level of the zero reference voltage. This second phase is known as the negative slope period and its duration depends on the output of the integrator in the first period. As the duration of the first operation is fixed and the length of the second is variable it is possible to compare the two and this way the input voltage is in fact compared to the internal reference voltage and the result is coded and is send to the display.急用，谢谢

Answer 1

一个模拟数字转换器，从现在起（ADC）的更好称为双斜率转换器或集成转换器。这种类型的转换器通常优于其他类型，因为它提供了准确，简洁的设计和相对漠视噪音变得非常可靠。电路的操作更好的理解，如果是分两个阶段描述。在第一阶段和一定时期的输入电压集成，在集成在这一时期结束时的输出，有一个电压是成正比的输入电压。在预设的时间，积分与内部基准电压和电路的输出美联储停止会逐渐降低，直至达到零参考电压水平。这第二个阶段就是所谓的负斜率时期，其持续时间对在第一阶段积分器输出而定。作为第一个操作时间是固定的，第二个变量的长度就可以比较两个这样的输入电压，其实是相对于内部参考电压，其结果是编码，然后发送到显示。
