<p>A pulse modulator (30) comprises a delay arrangement (32) for receiving a first sequence of pulses and for delaying each received pulse several times to obtain a plurality of sequences of pulses having different phases. The pulse modulator (30) further comprises a selection component (33) for receiving from the delay arrangement (32) a plurality of sequences of pulses having different phases, for receiving a modulating signal, wherein each possible value of the modulating signal is associated to one of the different phases, for selecting for each pulse of the first sequence of pulses a pulse of the respective sequence of pulses which sequence of pulses has a phase associated to a current value of the modulating signal, and for outputting the selected pulse as part of a pulse position modulated sequence of pulses. The invention relates equally to a modulating system comprising such a phase modulator and to a corresponding method. <IMAGE></p> |
