  1. Algorithms Output Input Digital Processing Typical approach to DASP systems development Algorithms are in the focus at development of any digital signal processing system. However they actually cannot be set up before it is clear how the input signal will be represented digitally.

  2. Algorithms ADC Output Input Digital Processing Sampling Quantizing Typical approach to DASP systems development Digitization of the input signal is a simple matter only in trivial signal processing cases. In general, the sampling and quantizing operations impact the features of the formed digital signal significantly.

  3. Algorithms ADC Output Input Digital Processing Sampling Quantizing Output specification Typical approach to DASP systems development Development of a DASP system starts at specification of its output in terms of the functions to be fulfilled and the quality to be provided for.

Typical approach to DASP systems development Organization of sampling and quantizing operations is carefully considered next targeting satisfaction of the specific processing requirements. Knowledge in the area of the corresponding DASP techniques is essential.
