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.
Lecture Notes 3 Sep 4, 2015. 1 Properties and Inverse of Fourier Transform. So far we have seen that time domain signals can be transformed to frequency domain by. the so called Fourier Transform. We will introduce a convenient shorthand notation to say. that x(t) has its Fourier Transform X(f) as. x(t)
