Abstract

In the processing of pulsed electrical signals of physiological origin (as well as signals from other sources), it is desirable to be able to provide a stable d.c. baseline and to suppress noise. This paper examines various design considerations for such a system and presents the complete electrical schematic for one design. Photographs of system performance are included.

Sommaire

Dans le traitement de signaux électriques impulsionnels d'origine physiologique (ou autre) il est souhaitable de pouvoir obtenir un niveau continu qui soit stable et de supprimer le bruit. Cet article examine les différentes considérations dont il faut tenir compte pour un tel dispositif et montre le schéma électrique complet ainsi que des photographies des résultats obtenus avec un tel système.

Zusammenfassung

Bei der Analyse von physiologischen und anderen elektrischen Impulssignalen ist eine stabile Gleichstrombasislinie und Rauschunterdrückung erwünscht. Die vorliegende Arbeit untersucht verschiedene Betrachtungen zur Konstruktion eines solchen Systems und liefert ein vollständiges elektrisches Schaltschema für eine Anordnung sowie Abbildungen zur Leistungsfähigkeit des Systems.
