Can someone from SE please revisit this request now that we're out of beta. Signal processing is sufficiently math heavy that it's sometimes required in meta discussions as well. For example, see this recent question.


Done (after a short hiccup that hopefully didn't inconvenience anyone). We usually do this when we turn MathJax on for the main site, somehow it fell through the cracks - sorry about that :) It's enabled now, enjoy.


let's see if it works for an answer: $$\begin{align} X(f) &\triangleq \int\limits_{-\infty}^{+\infty} x(t) \ e^{-j 2 \pi f t} \ dt \\ \\ x(t) &= \int\limits_{-\infty}^{+\infty} X(f) \ e^{+j 2 \pi f t} \ df \\ \end{align} $$ that seems to work too. Thank you Tim.
