Each voltage pulse Vp causes a magnetizing current im to be developed in the spurious self-inductance of each connected transformer, which if not compensated will cause a faulty voltage to arise after termination of the pulse and so result in faulty information transfer. The invention provides a controllable voltage source which generates a compensating current ic in the winding of each connected transformer to compensate this faulty voltage, so that at the instants of pulse termination the total magnetization of all transformers remains unchanged. | |
