| Abstract: | When several signals which all meet the dynamic range with different frequency are inputted the frequency counter, how to measure the frequency of the highest amplitude signal is the key which determine the design of the frequency counter measuring circuit. The article introduce a method of identifying the highest amplitude signal automatically by adding limiter in the measuring circuit. |
