Digital <bb>>signalb>bb>> processing - Wikipedia, the free encyclopedia

In order to use an <<bb>>bb>bb>>>analogb>bb>>bb>bb>>> <bb>>signalb>bb>> on a computer it must be digitized with an <<bb>>bb>bb>>>analogb>bb>>bb>bb>>> to digital converter (ADC).
Since the goal of DSP is usually to measure or filter continuous real-world <<bb>>bb>bb>>>analogb>bb>>bb>bb>>> signals, the first step is usually to convert the <bb>>signalb>bb>> from an <<bb>>bb>bb>>>analogb>bb>>bb>bb>>> to a digital form, by using an <<bb>>bb>bb>>>analogb>bb>>bb>bb>>> to digital converter.
Often, the required output <bb>>signalb>bb>> is another <<bb>>bb>bb>>>analogb>bb>>bb>bb>>> output <bb>>signalb>bb>>, which requires a digital to <<bb>>bb>bb>>>analogb>bb>>bb>bb>>> converter.

Modems (Linktionary term)

In contrast, digital-to-<<bb>>bb>bb>>>analogb>bb>>bb>bb>>> conversion can produce a near-perfect <<bb>>bb>bb>>>analogb>bb>>bb>bb>>> representation of a <bb>>signalb>bb>> so that no information is lost.
Modems (modulators/demodulators) are data communication devices that convert digital signals to <<bb>>bb>bb>>>analogb>bb>>bb>bb>>> signals, and vice versa.
Note that in the figure, the computer's outgoing digital <bb>>signalb>bb>> is converted to an <<bb>>bb>bb>>>analogb>bb>>bb>bb>>> <bb>>signalb>bb>> for transmission across the copper local loop to the CO.

Digital image processing - Wikipedia, the free encyclopedia

Digital image processing has the same advantages (over <<bb>>bb>bb>>>analogb>bb>>bb>bb>>> image processing) as digital <bb>>signalb>bb>> processing has (over <<bb>>bb>bb>>>analogb>bb>>bb>bb>>> <bb>>signalb>bb>> processing) -- it allows a much wider range of algorithms to be applied to the input data, and can avoid problems such as the build-up of noise and <bb>>signalb>bb>> distortion during processing.
Digital image processing allows the use of much more complex algorithms for image processing, and hence can offer both more sophisticated performance at simple tasks, and the implementation of methods which would be impossible by <<bb>>bb>bb>>>analogb>bb>>bb>bb>>> means.
Because of the computational load of dealing with images containing millions of pixels, digital image processing was largely of academic interest until the 1970s, when dedicated hardware became available that could process images in real time, for some dedicated problems such as television standards conversion.
