-Quantizationis also called discretization. We know the series of discretenumbersN = (1, 2, 3...), which incorporates the natural numbers. Discrete signifies, that this sequence includes separated elements which are not interconnected. The elements of our example areexactly such numbers, because the natural numbers do not include, for example, numbers between 1 and 2. Meanwhile, the sequence of real numbers R, as an example, iscontinuous: No matter how close two selected numbers are, there will continually be a number between them.
