Method for regenerating a synchronized signal from an input signal encoded in pulse regenerator hdb3 and to carry out the method.

摘要

Method for regenerating a synchronized signal with a frequency f * from input signal HDB3 symmetrical and coded, with the steps as follows: rectifying and transforming the input signal (HDB3) into a signal unbalanced input and treated so that it is proportional to the input signal (HDB3 =); generating an oscillator signal Osc with a frequency f by a VCO voltage controlled oscillator, characterized in that a rising edge of the signal processed input (HDB3 =) is detected by a phase control, a comparator is released phase, such that said phase comparator makes a comparison between the next falling edge of the signal processed input (HDB3 =) and the next rising edge of the oscillator signal Osc from the VCO, and such that the comparator phase is always turned off by the control phase, canceling the comparison, when the pulse of the input signal is zero; and generating a control voltage for the VCO by a loop filter from the filtered signal phase comparator, so that the frequency f of the oscillator is adjusted -through control- voltage in phase to the frequency f * of the input signal.
