Stochastic Signal Processing vs Geophysics made easy

Speech, music, seismic vibrations, oil prices, and climate measurements are all examples of stochastic (random) signals. In this textbook—intended for individuals with prior training in introductory signal processing and introductory probability theory—we develop techniques to process such signals to extract useful information. We present case studies ranging from music to photographic images to oil prices to climate data to the motion of individual biomolecules. This textbook, as an interactive textbook ("iBook"), makes use of your device's ability to display dynamic information through films and animations and to hear the results of the techniques applied to music. At the end of every chapter there are homework problems ranging from easy to "olympic". We make use of your device's interactive capabilities to offer 59 laboratory experiments in signal processing. The experiments use the camera, the microphone, the speakers, and the graphical user interface. These experiments are not simulations; they are examples of real digital processing of signals in your device. In this time of at-home and online learning, this is the way to learn signal processing through study and experimentation.

Discover the fascinating world of Geophysics, and how this science works in the search of accurate information about the Earth and other bodies in the Solar System. You will be surprised by the scope and applications of geophysical methods in the investigation of the Earth's structure, in the search for oil and minerals, in the search and assessment of groundwater contamination, and even in the determination of physical parameters of the Moon, Mars and of asteroids. The application describes, in a simple way and with a lot of beautiful illustrations, some of the main geophysical methods and their applications, explaining how we can determine the physical parameters of the interior of the planet using information from its gravity field, current and past magnetic field, heat flow, response to the propagation of natural and artificial seismic waves, and its behavior when subjected to an electric field or electromagnetic waves, for example. You will also find information about the career of geophysicist and the Brazilian institutions that offer the Bachelor of Geophysics course. Use it and disseminate it to people who want more information about this area of ​​activity and the profession.
