Multiple choice

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 S ($\omega$) = $\dfrac{16}{16 + \omega^2}$ 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 system which can perform the desired task could be:

  1. first order lowpass R-L filter

  2. first order highpass R-C filter

  3. tuned L-C filter

  4. series R-L-C filter
