Numerical Analysis of Analog Signals for Data Processing in Electrocardiology

The principle of a new data acquisition system is given for the numerical analysis of a visualized analogue signal. The operator chooses the sequence of interest. A 1/4 inch magnetic tape loop repeats the sequence on an oscilloscope screen. With numerical knobs he can either obtain automatically the full series of coded samples within the limits of a chosen zone of interest, or pick up the point by point coordinates of the only sample or segment he expects to be pertinent. The selected samples are brightened on the screen. The data are immediately made available in printed numbers to the physician for the patient’s medical file, or on punched tape for further processing and for Telex transmission.

Beschreibung des Prinzips eines neuartigen Datenerfassungssystems zur numerischen Analyse sichtbar gemachter Analogdaten. Der Operateur wählt die ihn interessierenden Impulsfolgen aus, die dann von einer Magnetband-Schleife auf den Bildschirm eines Oszilloskops reproduziert werden. Mit Hilfe von Schaltknöpfen kann er entweder automatisch die gesamte Folge der codierten Einzelsignale innerhalb des interessierenden Bereiches erhalten oder aber die Koordinaten der Segmente Punkt für Punkt abgreifen. Die ausgewählten Signalfolgen erscheinen auf dem Leuchtschirm, die entsprechenden Daten, stehen sofort entweder in gedruckter Form für die Krankengeschichte des Patienten oder als Lochstreifen für die weitere Analyse und die Telex-Fernübertragung zur Verfügung.
