Complex network based Fourier analysis for signal processing.

The design and construction of electronic circuits need the creation of innovative methods for analysing signals for increased performance, which led to the birth of the discipline of signal processing. Signal processing is a branch of electronics and electrical engineering that focuses on the creation and analysis of many types of signals, including electrical, electronic, sound, picture, and video signals. Both the characteristics of the signal and the outcome one wants to achieve decide the technique to be used. The present work is a novel attempt of employing complex network for signal analysis. The analysis of the Fourier component of a square wave reveals the untapped potential of complex network and graph properties. Investigation is also done into the changes that occur when the Fourier series' terms are added and how they affect the graph's features. [ABSTRACT FROM AUTHOR]
