摘　　要：压频转换作为一项信号处理与变换技术广泛应用于各领域。该文基于555定时器设计了一种成本低廉的压频转换电路,详细分析了其工作原理;基于Multisim软件设计了该电路的仿真实验。实验数据显示,该电路工作稳定,实现了电压-频率的线性转换,转换结果正确,误差为0.476%,转换精度为99.524%。Voltage- frequency- conversion,as a signal processing and transformation technology,is widely used in every field. In this paper,structure design and working principle of a new and low- cost voltage- frequency- conversion circuit based on 555 timer is discussed in detail. Moreover,simulation results based on Multisim soft show that the circuit designed in this paper is of its stability,linearity and correctness in voltage- frequency transformation. The converting precision of the proposed circuit achieves99. 524%,with error of 0. 476%.
