Question:

Use the periodogram algorithm to estimate the PSD of the following signal:

\[x(n)=\cos \frac{2 \pi}{4} n+x_{1}(n)\]

where

\[x_{1}(n)=-0.9 x_{1}(n-1)+x_{2}(n) \text {, }\]

where $x_{2}(n)$ is a white Gaussian noise with variance $\sigma_{X_{2}}^{2}=0.19$. Use in this case $L=512, L=1024$, and $L=2048$ and compare the results obtained in each case.
