Research on applying enzyme biological signal amplification system to DNA piezoelectric biosensor;

This paper introduced a kind of design method of the front signal conditioning module,the constant current source was structured by the four operational amplifier integration chip LM348,signal amplification circuit selected programmable ampl.

Using typical curves acquired from well analysis at early time based on small-signal amplification theory for well test interpretation,it is solved about the question of well analysis without radial flow.

How to distinguish different kinds of discharge signals of ESP (Electrostatic Precipitator) efficiently and exactly is very important for preventing ESP back corona fault and keeping ESP running stably.
