【摘要】 将3通道通用计数器、3通道DDS任意信号发生器、4 数字万用表的数字平台集成于FP GA内,设计出低功耗的模拟与控制电路,以Delphi实现虚拟图形化界面,在PC控制下虚拟地实现仪器集成,系统也可仅由单片机控制来实现系统智能工作方式,实验表明设计切实可行。更多还原

【Abstract】 A virtual integrated instrument controlled by PC was introduced, in which 3 lines’s common counter and 3 lines’s generation & 43/4 multimeter were integrated in digital plat FPGA,Delphi was designed for virtual pictorial manmachine interface, low power dissipation analogue and control circuit were designed. The instrument could also controlled by only single chip microcomputer to realize system intellect way,the experiment showed the design was feasible.更多还原
