Another name for FTIR is Fourier Transform Infrared Spectroscopy. It is a powerful scientific tool that is used in many fields. Visual interference, in which light waves split up and then come back ...

An interesting aspect of time-varying waveforms is that by using a trick called a Fourier Transform (FT), they can be represented as the sum of their underlying frequencies. This mathematical insight ...

Mathematical transforms can be a great help in understanding signals. Imaging trying to look at a complex waveform and figuring out the frequency components without the Fourier transform. [Artem ...
