Abstract
The circuit arrangement has a plurality of comparators (3, 4, 5) and the measuring voltage on the one hand and different reference voltages on the other hand are present at the inputs (8, 9, 10, 11, 12, 13) of the comparators, and the outputs (14, 15, 16) of the comparators (3, 4, 5) contain the measurement signal. Less effort than that in accordance with the state of the art is required in that the reference voltage for the second comparator (4) is controllable with the aid of the output signal of the first comparator (3) and that the reference voltage for the third comparator (5) is controllable with the aid of the output signal of the second comparator (4), and that the measurement signal can be represented with the aid of the total of all output signals of all comparators (3, 4, 5).
