The output voltage or current of a digital-to-analog converter is truly an analog signal.
The amount of deviation of the measured step size from the ideal step size is a measure of linearity.
In a digital storage scope, when memory is full, the next data point is lost.
The current across the MSB "rung" of a 4-bit R/2R ladder DAC if the reference voltage is 5 v and R is 8 Ω is 625 µA.
A sample-and-hold circuit is used in D/A conversion.
When the inputs of a four-bit D/A converter are connected to a binary up-counter, the output looks like an upward sloping line.
A data acquisition system may communicate via two common buses: the data bus and the control bus.
The output of an analog-to-digital converter is a voltage level.
When the analog input to a tracking A/D converter is at a constant level, the digital output will oscillate.
A DAC is monotonic if its output increases as its binary input is incremented from one value to the next.
