Digital phase comparators. |
摘要 |
<p>A novel method and apparatus providing an all digital phase comparator of two binary signals which employs a type of cross correlation of two binary signals and provides a 2bit binary word uniquely representative of phase alignment. The method can be carried out using a pair of flip-flop (FF) circuits, each FF having a clocking input and a data input, and where each FF has a delay in series with its data input. <IMAGE></p> |
