Advanced Sampling Theory

Sampling is a method of studying from a few selected items, instead of the entire big number of units. The small selection is called sample. The large number of items of units of particular characteristic is called population. The purpose of all the sampling techniques is to give the equal chance of any item to be selected without bias. Sampling theorems are Nyquist–Shannon sampling theorem, Statistical sampling and Fourier sampling. This book envisages on the proof of a number of theorems used in real life examples.
