Inventor: DOEMER JOSEF ING GRAD
IPC: H04B7/212
Filed: 1975-09-24
Abstract: Collected phase correction steps are added during a specified test interval. A frequency change step in the required sense is carried out in accordance with the phase correction steps. The test interval is shortened in steps, depending on the time elapsed between its beginning and reaching a specified value of the sum. At the end of such variable test interval the value of the frequency changing step in determined from the actual test interval and the sum obtained during it.
