摘要
介绍了两种频率测量的方法,并在此基础上引进分频技术提高了测量的精度。最后,应用该方法实现了测量声表面波CO气体传感器频率的具体装置。
Two methods of measure frequency are introduced,and based on these methods,the measuring accuracy is increased with aid of frequency division technique.Finally,a frequency measurement device is realized for SAW CO gas sensors using this principle.
