ABSTRACT:
In a signal processor, a sampling arrangement (SH11, S12, SH13, ADC1) samples at least a first signal (YA) and a second signal (UA, VA) so as to obtain sampled first signal (YD1) and a sampled second signal (UD1, VD1), respectively. A folding compensator (LPF11, LPF12, LPF13, SUB11, SUB12, MUX12) compensates for a folding component in the sampled first signal (YD1) on the basis of a spectral portion of the sampled second signal (UD1, VD1) that is substantially free of components that originate from the second signal (UA, VA).
