Introduction to Digital Filtering in Geophysics

Introduction to sampling and z-transforms. General characteristics of digital filter. Synthesis of digital filters from continuous filter data. Direct synthesis of digital filters. Filters with finite duration impulse responses. Fourier transform methods. Frequency sampling filters. Frequency sampling filters with interger multipliers. Quantization effects in digital filters. Optimization techniques in digital filter design.

Covering ideas and methods while concentrating on fundamentals, this book includes wave motion; digital imaging; digital filtering; visualization aspects of the seismic reflection method; sampling theory; the frequency spectrum; synthetic seismograms; wavelet processing; deconvolution; seismic attributes; phase rotation; and seismic attenuation.

Addresses the construction, analysis, and interpretation of mathematical and statistical models. The practical use of the concepts and techniques developed is illustrated by numerous applications. The chosen examples will interest many readers, including those engaged in digital signal analysis in disciplines other than geophysics.

This state-of-the-art survey serves as a complete overview of the subject. Besides the principles and theoretical foundations, emphasis is laid on practical applicability -- describing not only classical methods, but also modern developments and their applications. Students, researchers and practitioners, especially in the fields of data registration, treatment and evaluation, will find this a wealth of information.
