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.
As alternatives to the Fourier transform, in time-frequency analysis, one uses time-frequency transforms or time-frequency distributions to represent signals in a form that has some time information and some frequency information â by the uncertainty principle, there is a trade-off between these.he Fourier transform decomposes a function of time (a signal) into the frequencies that make it up, similarly to how a musical chord can be expressed as the amplitude (or loudness) of its constituent notes.
