This block calculates the standard deviation of its input signal. The standard deviation is the square root of the signal's variance:
y = sqrt( variance(u) )
The Variance block is used to calculate variance(u).
The parameter t_eps is used to guard against division by zero (the computation of the standard deviation starts at <simulation start time> + t_eps and before that time instant y = 0).
This block is demonstrated in the examples UniformNoiseProperties and NormalNoiseProperties.
