Is there any good everyday application of a convolution of 3 one-dimensional functions? How does that work? Trying to get some intuition around it. Something that maybe looks like: F ⚬ G ⚬ H= ∫ ∫ ∫f ⚬ g ⚬ h (I imagine there’d be 3 params for the pairs fg, gh, fh...?)

Often want to hit your sample in an excited state, so you pump it at wavelength (a) and prove it at wavelength (b). Then your instrument has some characteristic response function.
