| Abstract: | The design of EMG preamplifier for eliminating interference of 50Hz is presented. Satisfactory results are obtained by means of shielding preamplifier from electric and magnetic radiation, powering the detecting circuit with a DC DC isolated converter, floating reference ground of preamplifier and letting it be driven by common mode, etc. |
