The R-2R ladder DAC which is a binary-weighted DAC that uses a repeating cascaded structure of resistor values R and 2R. This improves the precision due to the relative ease of producing equal valued-matched resistors. The successive approximation or cyclic DAC, [4] which successively constructs the output during each cycle. Individual bits of ...
While in theory a DAC outputs a series of discrete Dirac impulses, in practice, a real DAC outputs pulses with finite bandwidth and width.Both idealized Dirac pulses, zero-order held steps and other output pulses, if unfiltered, would contain spurious high-frequency replicas, "or images" of the original bandlimited signal.
DAC, a form of 7+3 (chemotherapy) Microsoft Data Access Components, or Windows DAC, a framework of interrelated Microsoft technologies; Diamond anvil cell, a high-pressure device used in geology and engineering; Digital-to-analog converter, a system that converts a digital signal into an analog signal
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 ...
Figure 2: 4-bit linear R–2R DAC using unequal resistors. It is not necessary that each "rung" of the R–2R ladder use the same resistor values. It is only necessary that the "2R" value matches the sum of the "R" value plus the Thévenin-equivalent resistance of the lower-significance rungs. Figure 2 shows a linear 4-bit DAC with unequal ...

VGSY (ZYL) – Osmani International Airport – Sylhet; VGTJ (DAC - prior to 1981) – Tejgaon Airport – Dhaka; VH - Hong Kong. 1] Also see airport category and list.
The Covox Speech Thing is an external digital-to-analog converter (DAC) that plugs into the parallel printer port of a PC.It converts 8-bit digital sound using a simple R-2R resistor ladder into an analog signal output.
