摘要
采用由上至下逐层的方法,进行了自动频率测量仪电路的设计、综合、优化、仿真与验证。整个电路用一片PLD可编程器件作为载体,它可以测量频率在1Hz～10MHz范围的周期性信号。
This paper introduces a kind of automatic frequency measurer including circuits design, compostion, optimization, simulation and verification. The whole circuit takes a chip of PLD as carrier, which can measure cyclic signal that frequency is between 1Hz to 10MHz.
