Sampling Quantizing

Digitization of the input signal is a simple matteronly in trivial signal processing cases. In general, the sampling and quantizing operations impact the features of the formeddigital signal significantly.

Now, after it has been made clear how the digitizing will be carried out and how the digital signal will be represented, the development cycle can be concluded by choosing or developing the algorithm for the given specific task with the specific digital signal taken into account.
