摘要
针对涡街流量计中频谱分析功能对被处理信号的要求,采用跨导放大器与8X96系列单片机的软、硬件相结合,设计了具有适应涡街流量信号特点的具有自动控制增益功能的输入电路.
Against the requirements of the function of frequency spectrum analysis in vortex flowmeter on the processed signal, by using the hardware/software combination of transconduclance amplifier and 8X96 series single chip computer the input circuit with automatic gain control function is designed to meet the features of vortex flow signal.
