A Mobile Application to Demonstrate the Basic Concepts of Radio Electronics

In the process of studying the basics of the theory of signal transmission and acquaintance with the elements of electrical circuits it is important to demonstrate the mechanism of their work. For this, as a rule, a special laboratory workshop is required, inaccessible during lectures. The developed mobile application “SAoS” works in an interactive mode and does not require special programming skills. It allows the simulation of signals and operations on them using generators, adders, multipliers and various filters included in the structural diagram. The received signal is displayed in the form of an oscillogram and an amplitude spectrum.
