Proof that spectrum analyzer measures mathematical Power Spectral Density
It seems to me the power spectral density (PSD) is defined as follows. Consider a signal $X(t)$ The windowed version of this signal is
Consider a signal $X(t)$. We defined a time-windowed version of …

Proof that spectrum analyzer measures mathematical Power Spectral Density
@jithin 's answer gave me an idea that I think answers my question. I'm going to define a new window function:
$$
W_{\Delta t}(t) = \theta\left(t-\frac{\Delta t}{2}\right)\theta\left(\frac{\Delta t}{ …
