The following question refer to wide sense stationary stochastic processes
It is desired to generate a stochastic process (as voltage process) with power spectral density
By driving a Linear-Time-Invariant system by zero mean white noise (as voltage process) with power spectral density being constant equal to 1.
The parameters of the system obtained would be
First order R-L low-pass filter would have 
L = 1H
First order R-C high-pass filter would have C = 0.25F
Tuned L-C filter would have L = 4H C = 4F
Series R-L-C low-pass filter would have 
,
L = 4H, C = 4F
