DEVICE FOR RECORDING BIOELECTRIC POTENTIALS

摘要

The device for recording bioelectric potentials contains the electrometric amplifier with its differential inputs connected to the measuring electrodes and the output û with the inverting input of the operational amplifier. The non-inverting input of the operational amplifier is connected to the ground potential. In addition, the device contains two-threshold comparator with the inputs generating the thresholds connected to the output of the operational amplifier, and the information input connected with the auxiliary electrode and the output of the integral circuit. The input of the latter is connected to the output of two-threshold comparator representing the output of device as a whole.
