| Abstract: | Design of surface electromyography digital transducer was discussed.According to the special character of surface elec-tromyography and basic need of collection technology,it had been explored to investigate the electrode shape and the right placing method.The instrumentation amplifier INA128 was adopted to design preamplifier circuit.Active filter was designed and serial A/D switch circuit controller was used to output digital signal.Experiments showed that the design can improve ratio of signal and noise,reduce noise and detect surface electromyography effectively. |
