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.
External Links. The Fourier Transform is a tool that breaks a waveform (a function or signal) into an alternate representation, characterized by sine and cosines. The Fourier Transform shows that any waveform can be re-written as the sum of sinusoidal functions.ourier Series gives us a method of decomposing periodic functions into their sinusoidal components. The Fourier Series can also be viewed as a special introductory case of the Fourier Transform, so no Fourier Transform tutorial is complete without a study of Fourier Series.
