  2. Analog-to-digital converter - Wikipedia

    en.wikipedia.org/wiki/Analog-to-digital_converter

    Analog-to-digital converter. In electronics, an analog-to-digital converter ( ADC, A/D, or A-to-D) is a system that converts an analog signal, such as a sound picked up by a microphone or light entering a digital camera, into a digital signal.

  3. Digital-to-analog converter - Wikipedia

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

    In electronics, a digital-to-analog converter ( DAC, D/A, D2A, or D-to-A) is a system that converts a digital signal into an analog signal. An analog-to-digital converter (ADC) performs the reverse function. There are several DAC architectures; the suitability of a DAC for a particular application is determined by figures of merit including ...

  4. Integrating ADC - Wikipedia

    en.wikipedia.org/wiki/Integrating_ADC

    Integrating ADC. An integrating ADC is a type of analog-to-digital converter that converts an unknown input voltage into a digital representation through the use of an integrator. In its basic implementation, the dual-slope converter, the unknown input voltage is applied to the input of the integrator and allowed to ramp for a fixed time period ...

  5. Flash ADC - Wikipedia

    en.wikipedia.org/wiki/Flash_ADC

    Flash ADC. A flash ADC (also known as a direct-conversion ADC) is a type of analog-to-digital converter that uses a linear voltage ladder with a comparator at each "rung" of the ladder to compare the input voltage to successive reference voltages. Often these reference ladders are constructed of many resistors; however, modern implementations ...

  6. Successive-approximation ADC - Wikipedia

    en.wikipedia.org/wiki/Successive-approximation_ADC

    A DAC to convert the ith approximation xi to a voltage. A comparator to perform the function s(xi − x) by comparing the DAC's voltage with the input voltage. A register to store the output of the comparator and apply xi−1 − s(xi−1 − x)/2i. Operation of successive-approximation ADC as input voltage falls from 5 to 0 V. Iterations on ...

  7. Quantization (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Quantization_(signal...

    Quantization, in mathematics and digital signal processing, is the process of mapping input values from a large set (often a continuous set) to output values in a (countable) smaller set, often with a finite number of elements. Rounding and truncation are typical examples of quantization processes.
