ABSTRACT:
A device for filtering signals emitted by a medical device, principally an active implanted medical device. The device (26) receives an input that is a signal delivered by a circuit (16-24) that receives signals emitted by a medical device (10) in the form of a magnetic induction, in which the medical device has a metallic housing or case. A compensation stage (42) also is provided, having in the frequency domain a transfer function in the form: ##EQU1## where f.sub.c is a chosen parameter according to the geometry and the material of the metallic case of the medical device (10), and where j=.sqroot.-1. The device is useful with medical devices that emit sequences of messages formed by symbols belonging to an alphabet of n symbols (n.gtoreq.2), the compensation stage being able to reduce the rate of inter-symbol interference of collected signals that are applied to it.
