Conversions analogique-numérique et numérique-analogique (partie 1)

Absolute Accuracy: error of a data converter between input and output in the worst case and referenced to a voltage of one volt.

Accuracy: difference between measured value and true value; maximum error of a data converter with respect to the true value (cf. absolute accuracy and relative accuracy).

Acquisition Time: for a sample-and-hold device, the time required to change the holding capacitor charge by a value equal to the full-scale voltage, so that the error then remains below a specified error band.

Aperture Jitter Uncertainty: represents a random fluctuation of the sampling time due to stability errors of the ADC's internal clock generator. The amplitude error due to Aperture Jitter Uncertainty...
