2. Digital-to-analog converter - Wikipedia

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

   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: resolution, maximum sampling frequency and others. Digital-to-analog conversion can degrade a signal, so a DAC should be specified that has ...

3. File:Delta-Sigma Modulation ADC and DAC.svg - Wikipedia

   en.wikipedia.org/wiki/File:Delta-Sigma...

   English: Delta-Sigma Modulation ADC (top) and DAC (bottom) comparison block diagram. The actual delta-sigma modulation stage in each is identified by a curly bracket. Green arrows indicate analog signals, and blue arrows indicate digital signals.

4. Successive-approximation ADC - Wikipedia

   en.wikipedia.org/wiki/Successive-approximation_ADC

   Counter type ADC: The D to A converter can be easily turned around to provide the inverse function A to D conversion. The principle is to adjust the DAC's input code until the DAC's output comes within ± 1 ⁄ 2 LSB to the analog input which is to be converted to binary digital form. Servo tracking ADC: It is an improved version of a counting ...

5. Resistor ladder - Wikipedia

   en.wikipedia.org/wiki/Resistor_ladder

   Each tap of the string generates a different voltage, which can be compared with another voltage: this is the basic principle of a flash ADC (analog-to-digital converter). The main disadvantage is that this architecture requires 2 n {\displaystyle 2^{n}} comparators, one for each resistor; and this number cannot be reduced by using an R-2R ...

6. Delta modulation - Wikipedia

   en.wikipedia.org/wiki/Delta_modulation

   Delta modulation (DM or Δ-modulation) is an analog-to-digital and digital-to-analog signal conversion technique used for transmission of voice information where quality is not of primary importance. DM is the simplest form of differential pulse-code modulation (DPCM) where the difference between successive samples is encoded into n-bit data ...

7. Digital potentiometer - Wikipedia

   en.wikipedia.org/wiki/Digital_potentiometer

   Digital potentiometer schematic symbol example. A digital potentiometer (also called a resistive digital-to-analog converter, [1] or informally a digipot) is a digitally-controlled electronic component that mimics the analog functions of a potentiometer. It is often used for trimming and scaling analog signals by microcontrollers.

9. Zero-order hold - Wikipedia

   en.wikipedia.org/wiki/Zero-order_hold

   The zero-order hold (ZOH) is a mathematical model of the practical signal reconstruction done by a conventional digital-to-analog converter (DAC). [1] That is, it describes the effect of converting a discrete-time signal to a continuous-time signal by holding each sample value for one sample interval. It has several applications in electrical ...
