摘要:
A flip-flop circuit able to commute in correspondence with any logic transition of the input signal using a flip-flop and a logic gate of the EXNOR type receiving at its input a signal and the inverted output of the flip-flop. To the output of the EXNOR gate is connected a set-reset flip-flop which allows a reset to be effected after each commutation of the circuit in order to prepare it for the next transition.
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.
