3. Digitization - Wikipedia

   en.wikipedia.org/wiki/Digitization

   Internet Archive book scanner. Digitization [1] is the process of converting information into a digital (i.e. computer-readable) format. [2] The result is the representation of an object, image, sound, document, or signal (usually an analog signal) obtained by generating a series of numbers that describe a discrete set of points or samples. [3]

4. Data acquisition - Wikipedia

   en.wikipedia.org/wiki/Data_acquisition

   Data acquisition is the process of sampling signals that measure real-world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems, abbreviated by the acronyms DAS, DAQ, or DAU, typically convert analog waveforms into digital values for processing.

5. Digital-to-analog converter - Wikipedia

   en.wikipedia.org/wiki/Digital-to-analog_converter

   Digital-to-analog conversion can degrade a signal, so a DAC should be specified that has insignificant errors in terms of the application. DACs are commonly used in music players to convert digital data streams into analog audio signals. They are also used in televisions and mobile phones to convert digital video data into analog video signals ...

6. Successive-approximation ADC - Wikipedia

   en.wikipedia.org/wiki/Successive-approximation_ADC

   The successive-approximation analog-to-digital converter circuit typically contains four chief subcircuits: . A sample-and-hold circuit that acquires the input voltage V in.; An analog voltage comparator that compares V in to the output of a digital-to-analog converter (DAC).

7. Digital signal processing - Wikipedia

   en.wikipedia.org/wiki/Digital_signal_processing

   To digitally analyze and manipulate an analog signal, it must be digitized with an analog-to-digital converter (ADC). [7] Sampling is usually carried out in two stages, discretization and quantization. Discretization means that the signal is divided into equal intervals of time, and each interval is represented by a single measurement of amplitude.
