The first accumulator accumulates an in-phase integration result and a quadrature integration result over a time period. The first calculation unit determines a first evaluation value based on the accumulated in-phase integration result and the accumulated quadrature integration result. The second calculation unit processes the in-phase integration result and the quadrature integration result. The second accumulator accumulates the output of the second calculation unit over the time period. The multiplier determines a second evaluation value by multiplying the accumulated result from the second accumulator with a predetermined value. The comparator compares the first and second evaluation results wherein the comparison result is an indicator of the lock status. | 12-25-2008 |
