Counter circuit for controlling the operation of a quartz clock with one touch or fast electrical resetting of the time |
| 摘要 |
An electronic circuit for controlling an analog quartz clock, particularly for installation in automobiles, has first and second counters for generating control pulses at different rates according to whether the clock is to be operated in a normal mode, or a time-setting mode. In addition, a single 11-bit counter allows "fast" or "slow" resetting of the time by a single push button.
