Any set of data is a signal. In the sciences of the universe, data are sometimes provided in large amounts and processing them is a challenge in itself. But even in simple cases, it is useful to know the fundamentals: the notion of frequency, decomposition on a base of sinusoids, a Fourier spectrum etc.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
