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. 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 ...

4. Successive-approximation ADC - Wikipedia

   en.wikipedia.org/wiki/Successive-approximation_ADC

   The successive-approximation analog-to-digital converter circuit typically consists of four chief subcircuits: . A sample-and-hold circuit to acquire the input voltage V in.; An analog voltage comparator that compares V in to the output of the internal DAC and outputs the result of the comparison to the successive-approximation register (SAR).

5. 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.

6. 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 ...

7. Direct digital synthesis - Wikipedia

   en.wikipedia.org/wiki/Direct_digital_synthesis

   Figure 1 - Direct Digital Synthesizer block diagram. A basic Direct Digital Synthesizer consists of a frequency reference (often a crystal or SAW oscillator), a numerically controlled oscillator (NCO) and a digital-to-analog converter (DAC) [5] as shown in Figure 1.

8. Analog-to-digital converter - Wikipedia

   4-channel stereo multiplexed analog-to-digital converter WM8775SEDS made by Wolfson Microelectronics placed on an X-Fi Fatal1ty Pro sound card AD570 8-bit successive-approximation analog-to-digital converter AD570/AD571 silicon die INTERSIL ICL7107. 3.5 digit (i.e. conversion from analog to a numeric range of 0 to 1999 vs. 3 digit range of 0 to 999, typically used in meters, counters, etc ...

9. 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 ...
