Signal processing From Wikipedia, the free encyclopedia Jump to: navigation search Signal processing is an area of electrical engineering and applied mathematics that deals with operations on or analysis of signals, in either discrete or continuous time, to perform useful operations on those signals. Signals of interest can include sound images , time-varying measurement values and sensor data, for example biological data such as electrocardiograms control system signals, telecommunication transmission signals such as radio signals, and many others. Signals are analog or digital electrical representations of time-varying or spatial-varying physical quantities. In the context of signal processing, arbitrary binary data streams and on-off signals are not considered as signals, but only analog and digital signals that are representations of analog physical quantities. Contents Typical operations and applications History Mathematical topics embraced by signal processing Categories of signal processing ... edit Typical operations and applications Processing of signals includes the following operations and algorithms with application examples: Filtering (for example in tone controls and equalizers Smoothing , deblurring (for example in image enhancement Adaptive filtering (for example for echo-cancellation in a conference telephone, or

Digital signal processing From Wikipedia, the free encyclopedia Jump to: navigation search This article needs additional citations for verification Please help improve this article by adding reliable references . Unsourced material may be challenged and removed (May 2008) Digital signal processing DSP ) is concerned with the representation of signals by a sequence of numbers or symbols and the processing of these signals. Digital signal processing and analog signal processing are subfields of signal processing . DSP includes subfields like: audio and speech signal processing , sonar and radar signal processing, sensor array processing, spectral estimation, statistical signal processing, digital image processing , signal processing for communications, control of systems, biomedical signal processing, seismic data processing, etc. The goal of DSP is usually to measure, filter and/or compress continuous real-world analog signals. The first step is usually to convert the signal from an analog to a digital form, by sampling it using an analog-to-digital converter (ADC), which turns the analog signal into a stream of numbers. However, often, the required output signal is another analog output signal, which requires a

Signal Processing Signals and systems Filter implementation Spectral analysis System modeling Wavelet analysis Algorithm development Signal Processing Background Signals are inherent to nature and most man-made processes that influence human existence. They are attributed to numerous sources and typical examples include acoustic, vibration, biological and financial systems. Before it is possible to process a signal, it is first necessary to measure or collect the signal data using an accurate measurement method that does not distort or limit the signal content in any way. After the measurement, signal processing is then applied to the measured data in order to extract the information that is required. At this point, the person carrying out the analysis has to choose the most appropriate signal processing tool from a range of options. In order to select the right tools, it is not only necessary to have a clear understanding of the characteristics of the measured signal i.e. signal class, but also the signal processing technique and its limitations. Most people are familiar with classical time and frequency domain methods which often become the method employed because of habit and availability, even though they may not be the most suitable choice.

Help Catalogs Full Repository Repository Applets Repository Components Subject Catalogs Color Theory Viewing Techniques Signal Processing Texture Mapping ... 1D Fast Fourier Transform The Fourier Transform is a powerful tool allowing us to move back and forth between the spatial and frequency domains. Many of our explanations of key aspects of signal processing rely on an understanding of how and why a certain operation is performed in one domain or another. This applet helps students feel comfortable with these explanations, helping to build a strong intuitive grasp of how signals in one domain correspond to signals in the other. Convolution This applet allows students to understand the process of convolution by visually manipulating two functions through the process. It is useful in understanding both how convolution works and also what the effects are on specific signals being convolved together. Discrete Convolution This applet demonstrates how the idea of convolution which we have explored in the continuous domain can also be applied in the discrete domain that the computer operates in. The applet is identical in functionality to the 1D Convolution applet except that students adjust sample values rather than drawing continuous functions. Filter Shape This applet looks at how the shape of the two-dimensional cross-section of a filter affects the results generated when it is used to scale an image. Users are able to sketch and resize their own filters or use previously generated filters and see how each filter affects the scaling of a subregion of an image.
