<p>The invention relates to a method and an arrangement for generating cyclic pulses. A first differential pair includes an input for a first unipolar pulse, and a second input for a second unipolar pulse, the first unipolar pulse and the second unipolar pulse having inversed polarities with respect to each other. The first unipolar pulse and the second unipolar pulse are delayed in a delay-ing means, and a second differential pair includes an input for the first delayed unipolar pulse, and a second input for the second delayed unipolar pulse. The arrangement is configured to form a cyclic pulse by combining an output signal relating to the first unipolar pulse of the first differential pair with an output sig-nal relating to the second unipolar pulse of the second differential pair.</p> |
