Abstract:

This paper is aimed to design a preamplifier for bio signal such as electromyography (EMG) which records the muscular activity of the human body. Surface EMG are used because it assesses muscle function by recording muscle activity from the surface above the muscle on the skin. Surface electrodes are able to provide only a limited assessment of the muscle activity. The activity of the muscle are recorded in the form of waveform in the cathode ray oscilloscope (CRO).The input voltage, output voltage and the gain of the different muscular movements are tabulated.
