Understanding Unexpected Spectrum
The issue here is the resolution bandwidth of your measurement which is limited by the total observation time. I am guessing that your signal capture is on the order of 1 ms, such that if there was no ...

Mistake in Python implementation of Pisarenko's harmonic decomposition
By plotting all of the eigenvectors and not including their eigenvalues, you are trying to do MUSIC, but it won't work as I'll explain.
MUSIC (and Pisarenko's by extension) solve the equation
\begin{...

Cross Power Spectral Density of Three Signals?
Didn't have the chance to write out an answer until now, but wanted to at least provide some mathematical explanation for your options.
Let's say you have signals $x_{1}(t),x_{2}(t),x_{3}(t)$. What ...

Power Spectral Density and Total Power Calculation for Signal
Work in progress
The power spectral density of the signal that the OP is considering is most easily computed by first finding the Fourier Transform of $\Delta^2(1000t)$ and then using the Modulation ...
