Abstract:The project is about using the Electromyography (EMG) sensor to display the muscle movement and use connecting circuit to modify the signal from the EMG sensor. The modifying circuit connected to the EMG sensor include the amplifier circuit to amplify the signal, the filter to remove the DC offset and the high frequency noise, the rectifier for the positive swing of the signal and the envelope detector to smooth the signal. The circuit is designed according to the signal amplitude and the frequency spectrum an… Show more
