| Abstract: | The paper introduces the precise measuring circuit of ultra-low frequency voltage based on the characteristics of the measurement of ULF. The circuit can measure and disply the effective value and frequency of the voltage. The single-chip microcomputer is the core of the system. The paper narrates the structure and work theory of the system. |
