Tools for the evaluation of broadband signal tasks

The authors discuss the principle of physical similitude to obtain models suitable for the analysis and description of signal measurement tasks, whose character is evaluated quantitatively. In this context, the paper presents a simple example of using a broadband noise signal to investigate periodic structures, and it also characterizes the basic tests related to the described problem. The tested tasks are within the frequency range of between 100MHz and 10 GHz, and their execution is facilitated by a proposed measuring technique that exploits the potential of noise spectroscopy. The relevant equipment is also shown to complete the underlying analysis.
