<p>An intermediate frequency (IF) to baseband frequency signal converter (118) for decoding an analog IF signal (116) using phase information contained in the IF signal includes a first signal generator (122) for generating an analog square wave signal (124) from the IF signal. The signal converter also includes a second signal generator (136,138,139) for generating a local phase reference signal (134), and a phase difference determinator (132) for determining at a particular sampling interval a phase difference (148) between a phase of the analog square wave signal and a phase of the local phase reference signal, wherein the phase difference represents a symbol which the signal converter has decoded from the IF signal. <IMAGE></p> |
