Not in this detail, no. And I bet there many are CS curricula where fourier transforms aren't in the core courses (or even not explicitly present at all).

It's only relevant for some application domains (and has no "pure" CS use case I can think of), so a basic idea what it does, as a single lecture in a maths course or so, is probably enough in many cases. If you go in an field that uses it, you hopefully learn it in more detail there (or go googling for resources like this...).
