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.
The Fourier transform is called the frequency domain representation of the original signal. The term Fourier transform refers to both the frequency domain representation and the mathematical operation that associates the frequency domain representation to a function of time.
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.
