便携式电子计价秤的电路设计

Circuit Deign for the Portable ElectronicWeighing Scale

本文提出了一种便携式电子计价秤的电路设计方法，通过普通计算器的接口电路，可使计价秤的主体功能单元直接利用计算器实现，从而可降低成本．该设计亦适用于其它仪器电路中．

In this paper,a circuit design method is proposed for the portable electronic weighing scale The cost is lower because that the main functional elements of the electronic weighing scale is accomplished by comman calculators This circuit design is also adapted for other instruments circuitry
