CIRCUIT ARRANGEMENT FOR TIME-REGENERATION OF BROADBAND DIGITAL SIGNALS |
摘要 |
A circuit arrangement for time regeneration of digital signals comprises a correction circuit and a control circuit containing a low-pass filter. For time regeneration of broadband digital signals coded in a DC-free code in broadband digital signal switching and/or transmission systems, a correction element is inserted into the signal path and includes a digital signal input and a control input. The digital signal experiences an increased transit time at its signal edges of one sign in the correction element and simultaneously experiences a reduced transit time at its signal edges of the other sign based on the measure of each DC component occurring in the digital signal. The control circuit comprises a limiter which receives the digital signal and a low-pass filter connected to the limiter and to the control input of the correction element, the control circuit identifying such a DC component. |
