Thanks, that does make sense, and I'm quite happy with that in a different scenario. Let me explain...What got me thinking about this was trying to get to grips with Fourier Transform Infrared (FT-IR) Spectroscopy. In an FT-IR instrument there's a Michelson interferrometer and a light source...

Hi, I'm struggling with a conceptual problem involving the Fourier transform of distributions. This could possibly have gone in Physics but I suspect what I'm not understanding is mathematical. The inverse Fourier transform of a Cauchy distribution, or Lorentian function, is an exponentially...

Hi, I'm Jim, I'm a physicist and engineer in the UK. I've just started a new job in R&D, developing spectrometers so I'm having to brush up (hard) on various topics I studied as an undergraduate, which is the main reason I'm here.
