The Endocrine System Essentials. 1  The endocrine system is made up of a network of glands. 2  These glands secrete hormones to regulate many bodily functions, including growth and metabolism. 3  Endocrine diseases are common and usually occur when glands produce an incorrect amount of hormones.
What is a Fourier Series used for? Answer Wiki. The Fourier Transform is used to convert a continuous, periodic time domain signal, into the relative, instantaneous energy contained in the signal, across the entire frequency spectrum, and for *every* moment in time. This is what we call the frequency domain representation of that signal we started with.
The method of Fourier transform spectroscopy can also be used for absorption spectroscopy. The primary example is  FTIR Spectroscopy , a common technique in chemistry.he Fourier transform spectrometer is just a Michelson interferometer but one of the two fully reflecting mirrors is movable, allowing a variable delay (in the travel-time of the light) to be included in one of the beams. The Michelson spectrograph is similar to the instrument used in the MichelsonâMorley experiment.
