Radio time data reception procedure samples and stores received amplitude modulate signals for processing to reject short disturbances

摘要

A radio time data reception procedure samples and stores (XOO) a received amplitude modulated radio time signal (XO) detects transitions (X4, 5), measures their duration (T4, 5) and does not demodulate them if it is less than a preset value (Dt). Independent claims are included for a radio clock using the procedure.
