| abstract | PURPOSE: To reduce clock gain due to the repetition of current supply and power failure by performing the changing-over to the time of a backup time- piece at the time of power failure while performing the changing-over to a power supply synchronous time-piece at the time of power recovery and applying statistical processing to said time. n CONSTITUTION: A microcomputer 4A being a central processing circuit counts the pulse of power supply voltage subjected to waveform shaping by a waveform shaping circuit 2 to tick time as a power supply synchronous time-piece to display the same on a display device 5. When a pulse is not generated for a definite period, power failure is judged to change over time to a quartz time- piece 3. When the circuit 2 becomes a state generating a pulse, power recovery is judged to return to power supply synchronous time but, at this time, the count time of the first pulse from the circuit 2 is set to a time of the 1/2 cycle of a pulse, that is, statistical processing is applied to perform processing. Therefore, stable clocking operation reduced in error can be realized over a long period of time. n COPYRIGHT: (C)1991,JPO&Japio |
