摘要
文章根据电子设计自动化中频率计的计频原理,结合一些具体的仿真波形,介绍了提高频率计精度的方法,通过完善使得电路计算出的频率值更为精确且易于理解。进而介绍拓展可测信号频率的范围的方法,扩大了频率计的应用范围。
According to the working principle of cymometer in Electronic Design Automation, the paper combining with several idiographic simulating waveforms shows us the means to improve the measuring precision of cymometer. By perfecting, the circuit can be understood well and be used to calculate the frequency of signals more precisely. What＇s more, the paper introduces the method to expand the range of signal frequency that can be measured, which expands the use area of the cymometer.
