Description: 以单片机为中央控制器，设计一台出租车计价系统。系统中的直流电源由车载电源提供，电源电压为+9V~+24V。行驶里程传感器不需要设计，假设它具有汽车每行使1km提供1000个脉冲信号的特性。显示器可以采用LED数码管或LCD液晶显示模块。
应达到的技术指标：
1、 白天、晚上分别设置不同的里程单价，两位数码显示“X.X”,并用一键控制转换及
显示；
2、 两位数码显示车辆行使的里程数“XX”；
3、 营运起步价为5.00元，当小于3公里按起步价结算，当大于3公里时，按里程单价×里程数结算，并用三位数码显示“XX.X”；
4、 一键控制总价清除及开始计价，即按一下系统开始计价，再按一下时总价被清除（即用按键模拟出租车上的“空车”指示牌功能）。 -Single-chip microcomputer as the central controller, the design of a taxi meter system. System in the DC source is vehicle power supply, power supply voltage of+9 V ~+24 V. No mileage sensor design, assuming it has a car 1km each exercise provides 1000 pulses features. LED digital tube display can be used or LCD display module.
Should meet the technical specifications:
1, daytime, evening set different mileage unit, two digital display "XX", and conversion and with a key control
Display
2, the exercise of two digital display vehicle mileage "XX"
3, the operation starting at 5.00 yuan, while less than 3 km at prices starting at settlement, when more than 3 km, priced according to mileage × mileage settlement, and with three digital display "XX.X"
4, a key control and began to clear the total valuation, that valuation system began clicking, and then click when the total is cleared (ie, simulated with a taxi on the button "empty" sign function).

Description: 许多应用都要求通过高分辨率、差分输入ADC来转换单端模拟信号，无论是双极性还是单极性信号。本直流耦合电路可将单端输入信号转换为差分信号，适合驱动PulSAR系列ADC中的18位、1 MSPS器件AD7982。该电路采用单端转差分驱动器ADA4941-1 和超低噪声5.0 V基准电压源ADR435 ，可以接受许多类型的单端输入信号，包括高压至低压范围内的双极性或单极性信号。整个电路均保持直接耦合。如果需要重点考虑电路板空间，可以采用小封装产品，图1所示的所有IC均可提供3 mm × 3 mm LFCSP或3 mm × 5 mm MSOP小型封装。-Many applications require high resolution, the differential input ADC to convert single-ended analog signals, both bipolar and unipolar signal. The dc coupled circuit single-ended input signal can be converted into difference signal, suitable for drive PulSAR series of ADC
