Abstract:

An EMG (Electromyography) is a technique, which deals with the evaluating, analysis and recording the electrical activity emanating from skeletal muscles of the human body. The Electromyography is performed by using an instrument called an electromyograph, it produce the signal record on a graph paper called an electromyogram. The electrical activity of muscles is measured from surface gelled electrode placed on the desired muscles area. In this paper, we represent two circuitry portions to measure the EMG signals from two different muscles group at a time. The EMG signals from both circuits are fed in to an instrumentation amplifier to amplify the signals, having amplitude range ± 10 mV and need to filtrate the EMG signals with specific bandwidth range 20-500 HZ by using proper filter designs. The output EMG signals are shown in the LabVIEW software through computer, which is known as a real time multichannel EMG acquisition system.
