Power Spectral Density and Total Power Calculation for Signal
By the Wiener–Khinchin theorem, the power spectral density (of a power signal) is equal to the Fourier transform of the autocorrelation function. Therefore, one way to proceed is to analytically ...

Frequency content of a noisy signal
Couple of mistakes!
#1 Take the fourier transform of its power signal (square the noisy signal)
That's for anything but a constant zero signal not the same as the PSD estimate you get from your #2.

Finding mean, autocorrelation, and power spectrum of $y[n]=(x∗h)[n]$ where $x[n]$ is zero mean white gaussian noise
Assuming $h(t)$ is the impulse response of a linear system,
there are many ways to get to the desired result.
Here's one for the Power Spectrum:
By definition, the power spectrum $S_{y}(\omega)$ of a ...
