Abstract
An installation for the detection and, respectively, processing of electrical signals, in particular, physiological measuring signals, for example EKG, through the intermediary of a filter arrangement located in the measuring signal channel which is determinative of desired frequency components of the signals. The filter arrangement encompasses controllable means for the variation of the frequency range, as well as for the damping of the transmitted signal components; and which provides a control installation for effecting the control of the controllable means in dependence of the signal amplitudes in the sense whereby the transmission frequencies of the filter arrangement at signals with, in the normal case, relatively high or in contrast therewith still higher signal amplitude components, at an increase of the transmission damping, may be displaced in the direction of frequencies which are essentially significant for these high signal amplitude components; and for signals with abnormally low signal amplitude components, at a reduction of the transmission damping, may be displaced in the direction of frequencies which are essentially significant for these low signal amplitude comp…
