Abstract

In this chapter, we briefly introduce a few topics of signal processing that are quite used by the geophysicists, e.g. (i) Fourier series, (ii) the Fourier transform, (iii) the discrete, Fourier transform, (iv) the fast Fourier transform, (v) Shannon’s sampling theorem, (vi) linear filter, (vii) convolution, (viii) Z transform, (ix) autocorrelation, (x) cross correlation, (xi) autopower spectra, (xii) cross power spectra, (xiv) noise, (xv) robust statistics and robust processing.
