In this study, a brief analysis of the semiconductor era, the development of science and technology, made of semiconductor germanium, silicon and other materials was made. It is seen that analog electronics, which is used as a basic technology, contributes greatly to the development of other fields of science. In other technologies developed depending on this basic area, the pyramid structure is given according to the signal processing techniques and the order of development. Design techniques have been added to this pyramid depending on the signs used by the systems. The designs of the systems are generally determined according to the signal processing techniques, and the processes for modeling, simulation and standard production are also determined. In this, system design techniques, signal processing techniques, testing, durability and stages until the production stage are defined together.
