ELECTRIC CIRCUIT FOR AND METHOD OF GENERATING A CLOCK SIGNAL

摘要

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).
