method for the regeneration of a taktsignals from a hdb3 coded input signal and taktregenerator for implementation of the procedure

摘要

The input stage rectifies and converts the symmetrical input signal. The result is a non-symmetrical, processed signal proportional to the input. A voltage-controlled oscillator (VCO) produces an oscillator signal (Osc) at frequency (f). A phase comparator produces a comparison signal by comparing the falling edge of the processed signal with the rising edge of the oscillator signal. A loop filter prepares a control voltage for the VCO from the filtered comparison signal, such that the frequency of the oscillator is adjusted to be in phase with the frequency of the input signal. A control stage ensures that the phase comparator is always inactivated when an interruption pulse occurs in the input signal
