| Abstract: | A high common-mode disturbance,decaying and noice exist in the multi-dotted samplingand transmission of gas sensitive signals at long distance,This pepor explains that these problems can besolved by v-f conversion,and further points out that the converted frequence-modulated signals can betransmitted along power cable by means of direct current carrier economically.The signal sources ofgas sensors and interconnect of conversion and transmission are discussed.The related examples and re-sults are provided. |
