Abstract

1,240,061. A/D converters. SIEMENS A.G. 13 Aug., 1969 [28 Aug., 1968], No. 40444/69. Heading G4H. In a feedback converter each time the feedback voltage from digital/analogue converter 3 exceeds the input voltage U x , the state of a parity counting stage 4 is altered so that at the end of the conversion the state of the counting stage is dependent on the number of " I " bits in the digital output signal from control circuit 2. The state of the counting stage is then transmitted with the 7-bit signal, the arrangement being such that the 8-bit signal always has odd parity.
