An error caused by conversion of a variable having a continuous range of valves to a quantized form having only discrete valves, as in analog-to-digital conversion. The error is the difference between the original(analog) value and its quantized(digital) representation.  2, record 4, English, - quantization%20error

Record number: 4, Textual support number: 1 CONT

The ideal resolution of these converters is equal to the value of the LSB or 2-n for an n-bit converter. For A-D converters, associated with this resolution is an inherent quantization error, which reflects an uncertainty in the results of A-D conversion due to quantification of the analog signal.  3, record 4, English, - quantization%20error

Analogue-to-digital conversion (ADC) involves the conversion of the analogue voltage levels of an analogue signal into ones and zeros of a digital word.

In selecting an analog-to-digital converter for a particular CCD [charge-coupled device]] application, there is often a trade-off between cost and performance. Certain applications may require only low bit(i. e., coarse) resolution at very slow conversion rates. For example, the application may require only 4 bits of resolution at a 1-ms conversion rate for very low cost.  1, record 6, English, - conversion%20rate

In the field of ADC(analog-to-digital conversion), two main techniques are used : the successive-approximation technique, and the dual-slope integration. In the successive-approximation technique, an analog input value is compared to the analog value of a counter and progressively, a finer approximation is generated.  2, record 10, English, - successive%2Dapproximation%20conversion%20technique
