  • Circuit arrangement for the processing of physiological measuring signals
    Patent number: 3994286
    Abstract: A circuit arrangement for the processing of physiological measuring signals, in which there is provided a plurality of input amplifiers each having a positive and a negative input, whose output signals control a signal reproducing arrangement, and which are each connected to a collector electrode. Connected to the positive inputs of the input amplifier are the collector electrodes for the signals, and that resistors are located between the negative inputs and the outputs of the input amplifiers, the negative inputs being connected across the resistors with a common potential junction, and that the two inputs of a differential amplifier are connected to the outputs of respectively two input amplifiers, the output signal of the differential amplifier controlling the signal reproducing arrangement.
