设计要求：
出于不同目的的旅客对交通工具有不同的要求.例如,因公出差的旅客希望在旅途中的时间尽可能短,出门旅游的游客则期望旅费尽可能省,而老年旅客则要求中转次数最少.编制一个全国城市间的交通咨询程序,为旅客提供两种或三种最优决策的交通咨询.
//请保留此信息，谢谢
1.需求分析:
(1)提供对城市信息进行编辑(如添加或删除)的功能.
(2)城市之间有两种交通工具:火车和飞机.提供对列车时刻表和飞机航班进行编辑(增设或删除)的功能.
(3)提供两种最优决策:最快到达或最省钱到达.全程只考虑一种交通工具.
-design requirements : For different purposes to transport passengers have different requirements. For example, on official business travelers in the journey time as short as possible away tourists expect possible travel provinces, and elderly passengers asked the least number of transit. establishment of a national inter-city traffic advisory proceedings, for the visitors two or three best decision of the Transport Advisory.// Please keep this information, I would like to thank one. demand analysis : (1) to provide information on the city for editing (such as add or delete) function. (2) Town between the two modes : Train and aircraft. Schedules for the train and flights for editing (created or deleted) function. (3)

在集成电路中，通常采用T型解码网络实现数字量往模拟的转换，再利用运算放大器完成模拟电流变为模拟电压的转换。所以，要把一个数字量变为模拟电压，实际上需要两个环节，先把数字量变为模拟电流，这是由D/A转换器完成的；再将模拟电流变成模拟电压，这是由运算放大器完成的。有时D/A转换器芯片只包含前一个环节，有些D/A转换器则包含两个环节，用前一种芯片时，需要外接运算放大器才能得到模拟电压。-In integrated circuits, the usual T-decode digital networks to analog conversion, and then complete the simulation of the use of op-amp current into the analog voltage conversion. Therefore, it is necessary to become a digital simulation of voltage, in fact, need two links, first into a digital simulation of currents, this is determined by D/A converters completed then simulate current into the analog voltage, this is determined by computing completed amplifier. Sometimes D/A converter chip contains only a part before, some D/A converter includes two aspects, before a chip, the need for external op-amp voltage can be simulated.
