ABSTRACT:
A time signal receiver and decoder receives, detects and stores time information from time signals, e.g., WWV, WWVH, WWVB (USA), JJY (Japan), MSF (UK) and the like. The time information may be used for a self setting clock, and the clock may be used as a reference in time sensitive applications, devices and systems. The time signal receiver may use a high-Q state variable bandpass filter or an anti-notch filter circuit for selectivity at the time signal frequency of interest. The decoder is coupled to the time signal receiver, decodes the time information in the received time signal and may store the decoded time information.
