It is possible to develop more than 16 different analog levels using 4-bit resolution.

When analog inputs from several sources are to be converted, a multiplexing technique can be used so that one ADC may be time-shared.

A D/A converter changes things such as temperature variations into digital quantities.

When a DAC output shows a deviation of the measured step size from the ideal step size, this error is called nonlinearity.

In a digital storage scope, when memory is full, the next data point is lost.

In a counter-ramp A/D converter, the end-of-conversion line must be tied back to the clear input of the counter to change the circuit to perform continuous conversions.

D/A conversion is the process of taking a voltage or current and converting it to a digital code.

A data acquisition system may communicate via two common buses: the data bus and the control bus.

The time required to complete a conversion cycle is called conversion time.
