Abstract
A system and a method are provided for reducing noise in Electromyogram (EMG) signals from an external abdominal surface to detect uterine contractions. The system comprises an EMG sensor configured to detect a first EMG signal and to generate a corresponding EMG input signal and an EMG sensor configured to detect a second EMG signal and to generate a corresponding EMG input signal. A signal processor is coupled to the EMG sensor and the EMG sensor. The signal processor processes the EMG input signal and the EMG input signal with a filter and sum technique to generate an EMG reduced noise signal that represents a magnitude of at least one contraction event and periodicity of a set of multiple contraction events.
