| Abstract: | In order to solve the transnormal error which measured by the Honeywell HPA200 precision barometer,factors that related to the phenomenon are compared.The EMI characters of the HPA200 barometer have been found that the basic factor is the 400 MHz wireless interphone.Then,the hardware of the LC band reject filter is designed to lower the measure error value by the HPA200 precision barometer.The measure error is obviously reduced by the HPA200 barometer with the LC band reject filter in practice,and the abili... |
