| Abstract: | The design of the 8051 microprocessor core based on the time difference method for the high-precision measuring system. With the amplifier gain from the change, and receiving a low-pass filter to eliminate the interference band-pass, temperature of the modified terms, the increase in threshold voltage comparator circuit echo improved accuracy. |
