Parameters	Description
Mean	$\overline{x}=\frac{i}{N_s}{\displaystyle \sum }_{i=1}^{N_s}x\left(i\right)$
Standard Deviation	$F_s=(\frac{1}{N_s}\sqrt{{\displaystyle \sum }_{i=1}^{N_s}{\left(x\left(i\right)-\overline{x}\right)}^2}$
Root Mean Square (RMS)	$F_s=\sqrt{\frac{1}{N_s}{\displaystyle \sum }_{i=1}^{N_s}{\left(x\left(i\right)\right)}^2}$
