Abstract
A method and system for producing higher quality electromyogram (EMG) signals utilizes an array of electrodes for sensing a plurality of EMG signals in an electrically active region of a subject's muscle. A weighting function is applied to the EMG signals to produce weighted signals. This weighting function contains correction features for the relative locations of the center of the electrically active region and the electrodes. The quality of the weighted EMG signals is evaluated, and the weighted signals or sum or mean of the weighted signals whose evaluated quality is insufficient are replaced. A sum or mean of a feature of the weighted signals is calculated to produce a higher quality electromyocardiographic signal. The method and system can also be used to determine signal strength or frequency contents of a signal falling outside the array of electrodes.
