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 Ventilator Validation Kit supports new prototype development, existing design validation for production testing, mobile field testing and verification, and other uses where accurate pressure and flow measurements are critical.
