Abstract

1444682 Analogue-to-digital conversion W & T AVERY Ltd 23 Jan 1975 [25 Jan 1974] 03567/74 Heading H3H In a dual ramp analogue-to-digital converter, error due to offset and drift is reduced by reversing the polarity of the input analogue and reference voltages for alternate conversion cycles and averaging the moduli of the digital outputs. The analogue input may be from a strain gauge bridge circuit. Suitably,
