Abstract
In the apparatus disclosed herein, a data signal to be phase adjusted is applied to a plurality of delay lines providing progressively greater delays. The outputs of the several delay lines are compared over a period of time and a selection of one of the output signals for utilization is made based on choosing that delay line output which is in opposition to that pair of outputs which straddles or encompasses the most transitions.
