Abstract:
1. Method for detecting a beginning of dips in amplitude in an output time-signal of a time-signal receiver identifying a beginning of a respective seconds in the time-signal, said method comprising the steps of: sampling the output time-signal of the time-signal receiver N-times per second; storing N sampled values in respective cells of a memory with N cells; generating, in the memory, a mean signal curve for a time interval of one second over a period of several seconds by repeating each of the sampling and storing steps and accumulating the sampled values in the respective cells during the period of several seconds; and determining a beginning of a dip in the output time-signal to identify the beginning of a respective second in the time-signal by identifying a position of minimum value of the generated mean signal curve, and thus a beginning of the seconds in the time-signal.
