DEVICE FOR RECOVERY OF CLOCK FREQUENCY IN DIGITAL TRANSMISSION |
摘要 |
<p>A DEVICE FOR RECOVERY OF CLOCK FREQUENCY IN DIGITAL TRANSMISSION The device for recovery of the clock frequency of a digital signal comprises a rectifier, a filter having a very narrow bandwidth coupled to the first input of a phase comparator of analog type, a controlled oscillator, the output of which delivers the recovered clock signal and is coupled to the second input of the phase comparator via a low-pass filter. The output of the phase comparator is connected to the input of a loop filter, the output of which is connected to the control input of the oscillator.</p> |
