Abstract
A method for processing an input composite signal includes tracking a signal component of the input composite signal according to a frequency of a pilot signal to generate a locked signal, detecting an amplitude of the signal component to generate a detecting result, and generating a reproduced pilot signal according to the detecting result and the locked signal. A frequency and a phase of the locked signal are substantially identical to the frequency and a phase of the pilot signal.
