ABSTRACT:
A combined PLL and ALL module for switching FM signals includes a PLL unit and an ALL unit electrically connected therewith. The PLL unit is used to initially process FM signals received from a co-channel. Outputs of the PLL unit are sent to the ALL unit and processed therein. The PLL unit and the ALL unit are controlled to process the FM signals by adjusting the ratio of second amplitude to first amplitude to closely approach a predetermined value such that the two FM signals are switched.
