Abstract
A device for detecting electric potentials of the body of a patient has measuring electrode inputs (Y, . . . , Y) connected with and a plurality of outputs (A, . . . , A) via amplifiers (Op, . . . , Op). A summing unit () is connected with the outputs and outputs a mean value of the signals (E, . . . , E) output by the amplifiers. Common mode signals are removed from the signals (E, . . . , E) by a subtracting unit () which subtracts the output of the summing unit, amplified by an amplification factor (1/β), from at least a portion of the output of the subtracting unit. The output of the subtracting unit is connected with the inputs of the amplifiers. The subtracting unit amplification factor (1/β) and an amplification (β') of the amplifiers for the output of the subtracting unit are adapted, such that the reciprocal value of the amplification factor (1/β) corresponds to the amplifiers amplification (β′).
