Apparatus, including a first signal source generating a first signal and a second signal source generating a second signal. A cross-over switch is connected between the two sources so as to generate in a direct switch configuration a sum of the first and second signals and in a crossed switch configuration a difference between the first and second signals. The apparatus includes a processor which is configured to receive the sum and the difference, and to recover the first signal and the second signal therefrom.
