Title (EN) PHASE ANGLE MEASUREMENT USING RESIDUE NUMBER SYSTEM ANALOGUE- TO-DIGITAL CONVERSION
(FR) MESURE D'ANGLE DE PHASE AU MOYEN DE LA CONVERSION ANALOGIQUE-NUMÉRIQUE À SYSTÈME DE NUMÉRATION DE RÉSIDUS
Abstract:
(EN) A phase angle can be measured between an analogue signal and a reference signal by converting the analogue signal to digital samples in a residue number system (RNS) analogue-to-digital converter (ADC), based on a RNS scheme. The phase angle can be measured directly from the RNS values output by the RNS ADC, or the RNS values can be converted to a binary scheme, such as straight binary, offset binary or two's complement, before calculating the phase angle measurement.
(FR) Un angle de phase peut être mesuré entre un signal analogique et un signal de référence en convertissant le signal analogique en échantillons numériques dans un convertisseur analogique-numérique (CAN) à système de numération de résidus (RNS) basé sur un principe de RNS. L'angle de phase peut être mesuré directement à partir des valeurs de RNS produites par le CAN à RNS, ou les valeurs de RNS peuvent être converties vers un principe binaire, par exemple binaire direct, binaire décalé ou complément de deux, avant le calcul de la mesure d'angle de phase.
