ABSTRACT:
An electric circuit (30) for generating a clock-sampling signal (CLK) for a sampling device (31) comprises a clock generator (1, 40, 50, 60) for generating a plurality of clock signals (21-24, 51-54, 61-64), a correlation device (L) for correlating a characteristic signal section (LE) of a digital signal (DS) with the plurality of clock signals (21, 22, 23, 24, 51-56, 61-64), and a selecting device (MX) for selecting one of the clock signals (21, 22, 23, 24, 51-55, 61-64) as the clock-sampling signal (CLK) for the sampling device (31) on the basis of the correlation by the correlation device (L). The clock signals (21-24, 51-54, 61-64) have the same cycle duration (T) and are phase-shifted with respect to each other. The sampling device (31) subsequently samples the digital signal (DS) with the clock-sampling signal (CLK).
