The method for expanding the control-range of AFC involves a frequency-controlling technology. The method is to move the control-range of AFC by tracing synchronous signals to expand the control-range and lock the signals in the new scope. The beneficial effect of this invention is to expand the control-range of AFC through searching the simultaneous signals compulsively, so the signals can also be locked even though the frequency deviation is great. |
