Even under field conditions the registration of EMG-signals is often interfered with artifacts. For quantitative signal processing it is necessary to eliminate artifacts and noise from the EMG raw data. We show a simple and efficient way with the help of a recursive digital first order Butterworth filter. This filter-type has a great slope steepness and requires minimal calculations. The algorithm is derived and easily programmable.
