Signal Quality Check
The dEMG acquisition software comes complete with our patent-pending Signal Quality Check to ensure that you record high-quality sEMG data. The Signal Quality Check provides feedback on important signal properties including: 1) the Signal to Noise Ratio (SNR); 2) the amplitude of the Baseline Noise, which reflects the skin-electrode interface; and 3) the amount of Signal Clipping and Line Interference (i.e. interference from power lines and other sources). Preserving the fidelity of the sEMG signals you record is yet another way the dEMG System ensures reliable decomposition results.
Use the Signal Quality Check to:
Identify the location of the sensor on the muscle for high amplitude sEMG signals
Examine whether skin preparation is adequate for recording decomposable sEMG signals
Check sEMG signal quality throughout your experiment
Improve the quality of your sEMG data
