ABSTRACT:
A method for tracking a received signal comprises the steps of setting (635) a counter (130) to a first value indicative of a first signal voltage, determining a center threshold of the received signal, and determining a number of center transitions of the received signal within a predetermined time period. The method further comprises the step of automatically decrementing (685, 695) the counter (130) to a second value indicative of a second signal voltage in response to expiration of a predetermined amount of time, wherein the second value differs from the first value by a predetermined amount determined by the number of center transitions of the received signal within the predetermined time period.
