Abstract
Device for cancelling the effects of the reflection in a signal transmission system ( ) including a driver ( ) and a plurality of n receivers ( ) wherein signals are sent according to a multipoint topology from the driver to the receivers, each receiver having an internal capacitance and sending back reflection signals to the driver each time a signal is transmitted thereto by the driver. The device comprises circuit means causing the signal resulting from the sequential reflections due to a given receiver and then due to the driver to have the same magnitude but the reverse sign as the sum of all signals received in the given receiver resulting from the reflections due to all receivers, and the net linking the driver to each receiver comprises delay means ( ) enabling the propagating time of a signal sent from the driver to this receiver to be identical for each receiver, whereby the total sum of all reflection signals arriving in the given receiver at the same time is equal to zero.
