Verfahren und Vorrichtung zum Kombinieren von von Meßfühlern abgegebenen Signalen

摘要

Analog signals picked up by sensors are oversampled and converted locally for example into streams of 1-bit digital words and, without any previous formatting are transmitted on transmission channels to a central station. The central station includes a storage and a combining circuit for combining and weighting directly these 1-bit words, as well as a filter for reconstituting, from the combinations, high-resolution digital words. A preferred application is combining of acoustic or seismic signals.
