WebConsider a zero-mean, stationary, discrete-time stochastic process having power spectral density S zz(θ) = ∣ejθ −2∣21 +1. Do the following: (1) Determine a Gauss-Markov model for the process. (2) Determine the canonical spectral factor g(z) for S zz(θ), i.e., that S zz(θ) = g(ejθ) 2 while g is stable and stably invertible. WebThe periodogram is based on the definition of the power spectral density (see Appendix C). Let denote a windowed segment of samples from a random process , where the window function (classically the rectangular window) contains nonzero samples. Then the periodogram is defined as the squared-magnitude DTFT of divided by [120, p. 65]: 7.7
