A frequency control system (126) for locking the frequency of a receiver, susch as a receiver portion of a transceiver, to the frequency of a transmitter, such as a base station. The frequency control system (126) is operable to determine a center, or other reference, frequency of a signal, either a conventional analog signal, or discrete, encoded signal. The frequency control system may be advantageously embodied in a dual-mode radiotelephone operable to receive both conventional, analog signals and discrete, encoded signals.
