Data analysis for the graphic representation of measurement data
Deep-sea echo sounding, for example, provides a very large amount of the most various measurement
data, which after being interpreted physically (i.e. subjected to various mathematical and physical
processes) must finally be available in an ordered presentation, here as the relief map of a deep-sea rift.
The interpretation of measurement data of the most various kinds, their processing and presentation in a
structured form is increasingly becoming an essential vocational qualification. (Source: Krupp-Atlas

• Communications technology is more and more synonymous with computer-aided
signal processing. Digital signal processors which are optimised for such operations
are used more and more and today make possible the real time processing of two-
and multi-dimensional signals - i.e. pictures.
• As at present and even more so in the future a communications system can be repre-
sented by a program of linked algorithms. There is now the possibility of placing the
individual components of a system as a "virtual" component on the screen by a mouse
click and by joining up these components to form a block diagram and thus generating
a virtual system (VS). At the same time the appropriate algorithms are linked in the
background, i.e. by adding important sub-programs (for mathematics and graphics)
they are linked together for the overall process.
• Virtual systems provide real results by means of hardware (computer, peripherals)
and the programs which forms the virtual system. It is impossible to tell from the
outside whether the signal processing was carried out on a purely hardware basis or
by using a virtual system -i.e. a program.
