Electrical circuit including a first array (22) and a second array (16) of electrical components mounted on a circuit board having an electrically conductive cladding (20), comprising a system for interconnecting the components of the first array to the components of the second array with parallel signal channels. In each of the channels, there is one electrically conductive strip (48) formed within the cladding (20) and providing for a path of current from a component of the second array to a component of the first array. A second conductive path is provided for conducting current from the first array to the second array. The conductive strip forms therewith a portion of a loop which generates a magnetic field in the presence of currents flowing through the two paths. There is magnetic coupling between the paths of one channel to the paths of the other channel, the magnetic coupling provided by the wire loops having a positive coefficient of mutual inductance while the coupling from loops lying in a plane parallel to the padding is characterized by a mutual inductance of negative coupling coefficient. The positive and the negative mutual inductances tend to cancel for reduction of crosstalk among the channels.
