The analysis of the EMG signal in the frequency domain involves measurements and parameters which describe specific aspects of the frequency spectrum of the signal. Two parameters of the power density spectrum may be easily used to provide useful measures of the EMG frequency spectrum. The two measures of interest are:
If the EMG spectrum has a normal distribution, the Median and Mean frequencies will be identical. Any deviation from normality will result in differing values for the Median and Mean frequencies.
The Dual Wireless Respiration and ECG BioNomadix module pair consists of a matched transmitter and receiver pair optimized for respiration and electrocardiogram data; record one or both signals. RSP (CH A)–measure abdominal or thoracic expansion and contraction while breathing ECG (CH B)–record electrical activity generated by the heart The high signal to noise ratio and […]
View AllBIOPAC provides researchers with a complete range of tools to gather data on heart rate variability (HRV). The following studies demonstrate just some of the ways in which HRV research benefits from the implementation of BIOPAC hardware and software solutions. PTSD and HRV Post-traumatic stress disorder (PTSD) has been associated with dysfunction of the autonomic […]
