Abstract:
1. A method for controlling the sampling phase of a signal that is to be regenerated by sampling, comprising: performing n-fold oversampling of the signal with n≧3, wherein n is an integer, in order to obtain n samples A(i) for n sampling phases AP(i) per period duration T of the signal with i=0, 1, . . . n−1; calculating differential errors Delta(i, i+m)=A(i+m)−A(i) between at least two respective samples A(i+m) and A(i) for at least two different i from i=0, 1, . . . n−2 and at least one m with m≧1 with m+i≦n; summing the differential errors Delta(i, i+m) for the at least two different i from i=0, 1, . . . n−2 and the at least one m with m≧1 with m+i≦n; calculating moving differential error averages SumDelta(i, i+m) of the summed differential errors Delta(i, i+m) for the at least two different i from i=0, 1, . . . n−2 and the at least one m with m≧1 with m+i≦n over a predetermined number of sampling periods T′; comparing at least two moving differential error averages SumDelta(i, i+m) of the summed differential errors Delta(i, i+m) for the at least two different i from i=0, 1, . . . n−2 and the at least one m with m≧1 with m+i≦n, in order to obtain at least one comparison result; and using the at least one comparison result to decide which of the n sampling phases AP(i) the samples have the least discrepancy from an actual signal value on average for selection as a reference sampling phase.
