Abstract:ABSTRACT. Signal processing is a set of techniques used to extract data from any signal. A signal may be mathematically characterized as a function of several variables (parameters), such as time, distance, resistivity, or radiance. A signal is usually acquired using one or more analog or digital devices, such as a temperature sensor, a digital camera, or a resistivity probe. After acquisition, the processing depends on the nature of the signal and its information. In addition to the information being studied,… Show more
