Electromyogram or EMG signal are very small signal, it require a system to enhance to display or for further analysis process. This paper presents the development of low cost physiotherapy EMG signal acquisition system with two channel input. In the acquisition system, both input signal is amplified with a differential amplifier and undergo signal pre-processing to obtain the linear envelope of EMG signal. Obtain EMG signal is than digitalized and sent to the computer to be plotted.
