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.
1 In sampled systems, inputs and outputs are related by difference equations and Z-transform techniques are used to solve those differential equations. 2  An analog signal is converted to a digital form in an A/D. 3  The digital signal is processed somehow. There are tools that you have available from work with Laplace transforms. 2  For example, with two real poles you should be able to divide the transform into two parts, each with one real pole, using partial fractions.
