For data to be reliable and valid, the signal must be virtually artifact-free. If it is not, then the data is often unreliable or invalid, which renders it useless. The Noraxon signal conditioning system uses an electronic feedback technique to cancel out very low frequency changes (dc to a few Hz) in the acquired physiological signal. Signals in this very low frequency range can arise because of the motion artifact phenomena. The Noraxon signal is remarkably free of noise caused by skin or cable movement and offers a very stable baseline. With Noraxon’s patented system, information carried by the overall signal is effectively split into an “EMG only” component and a low-frequency “motion artifact” component. The motion artifact component is literally subtracted from the overall signal allowing only the EMG signal to be presented.
