Frequency-domain features mathematical representation.

Parameters	Description
Power	Power in the frequency band
Median Frequency	${{\displaystyle \int }}_0^{MF}P\left(\omega \right)d\omega ={{\displaystyle \int }}_{MF}^{\infty }P\left(\omega \right)d\omega =\frac{1}{2}{{\displaystyle \int }}_0^{\infty }P\left(\omega \right)d\omega$
Mean Power Frequency	$MPF=\frac{{{\displaystyle \int }}_0^{\infty }\mathsf{\omega }P\left(\omega \right)d\omega }{{{\displaystyle \int }}_0^{\infty }P\left(\omega \right)d\omega }$
