Abstract
An installation for the detection of and, respectively, processing of electrical signals, particularly physiological measuring signals, for example EKG, through the intermediary of a signal rectifier, and a thereto connected threshold discriminator having a threshold adjusted to a predetermined amplitude value of the rectified signals. The installation includes a signal polarity detector which is actuated by the threshold discriminator and, at the instant of exceeding or transgressing of the threshold of the threshold discriminator, detects the polarity of the threshold exceeding signal amplitude preceding the rectifier, and which superimposes upon the signals preceding the rectifier a direct potential having a polarity in conformance with the detected signal polarity until at least the occurrence of the subsequent exceeding of the threshold, and wherein the direct potential indicates an amount lying between zero and the threshold level of the threshold discriminator.
