This invention relates to the field of electronic timekeeping.

Electronic clocks on multistable elements with digital indication are known, which contain a master oscillator, a constant oscillator, a frequency divider, recalculated decades, logical devices, blocks for allocating time, made in the form of coincidence circuits and time matching circuits, and a display unit 1. However, in these hours the timestamps of the minute, the hours are generated with a significant delay, i.e., the watch has a dynamic error when issuing timestamps.

The closest to the technical essence of iK proposed are electronic clocks on multistable elements with digital indication, containing a series-connected master oscillator, phase constant generator, coincidence circuit, frequency divider, counting phases of units and tens of seconds, minutes, hours, and also the display unit and time tagging blocks, made in the form of coincidence circuits and multi-time coincidence circuits, the output of the master oscillator connected to the clock inputs of the phase-pulse counting decades 2. In such hours, significant instrumental costs are required for recalculating control in phase-pulse decades.

For the sake of simplicity, four D-flip-flops are introduced at the proposed time. And the inputs

trigger synchronization is connected to the second, fourth, fifth, and sixth decade respectively, the inputs for setting the first and second triggers are connected to the output “5, the third trigger to the output“ 1 of the phase constant generator, the inputs D of the first and second triggers are connected to output "About, fourth trigger - with output" 2 phase constant generators, third trigger - with output matching circuit, whose inputs (connected to the direct output of the fourth trigger and output "4 phase constant generators, direct outputs of the first and second flip-flops connected to inputs of recording the second and fourth decades, third trigger - to the inputs of the recording and schestoy fifth decades, and the frequency divider input connected to the output "9 generator phase constants.

The drawing shows a block diagram of the clock “a

multistable elements with digital display.

The clock contains a series-connected master oscillator 1, a generator 2 phase constants, a frequency divider 3, pulse-counting counts 4.1-4.6, and

D-griggers 5.1-5.4 control of the decal recalculation module, a coincidence circuit 6, an indication device 7.

The output of the master oscillator 1 is connected to the clock inputs of the phase-pulse counting decades, the outputs of which are connected to the display device. The entrances to the D-triggers are connected to the outputs of decades 4.2, 4.4, 4.5, and 4.6, respectively. The inputs for setting zero D-driggers 5.1 and 5.2 are connected to the –output of the constant “5, and the input for setting zero of the trigger 5.3 is connected to the output of the constant“ 1 of generator 2. The inputs D TipHrreipoe 5.1 and 5.2 are connected to the output of the constant “O, trigger 5.4 - with output Constants "2 oscillators 2. D trigger input 5.3 is connected to the output of the coincidence circuit 6, the first input of which is connected to the right 1mo trigger output 5.4, and the second input to the constant output 4 of the oscillator 2. Direct trigger output 5.1 is connected to the input is over a decade of 4.2, H1p is my trigger output 5.2 - with a recording input of decade 4.4, and trigger 5.3 is with recording entries of decades 5.5 and 5.6.

The pulses from the output of the generator 1 are received “and the input of the generator 2 and the clock inputs of decades 4.1–4.6. The pulses from the output of the “5 generator 2” come to the inputs of setting zero of the triggers 5.1 and 5.2, which set the decades 4.2 and 4.4 to the initial state (the temporal position of the output pulses of these decades is the same as the coistant “4). The pulses from the output "1 of the generator 2 arrive at the input of the zero setting of the trigger 5.3, which sets decades 4.5 and 4.6 to the initial state (the temporary position of the output pulses of these decades coincides with the constant" O), from the output "9 of the generator 2, the pulses arrive and the divider input frequencies 3 and further with a frequency of 1 Hz are fed to the counting input of the lower decade 4.1. During this decade, a series of states pass through, accumulating information: about time.

The time counting is ensured by the prohibition of clock pulses by counting AND pulses arriving at the input of the younger decade 4.1. The sixth counting pulse appears at the output of decade 4.2 and arrives at the input of decade 4.3, increasing its state by one. Next, at the output of decade 4.2, the tenth clock pulse appears, whose temporal position coincides with the constant "O. It arrives at the trigger synchronization input of 5.1, to the input D of which pulses are received from the output of generator 2 and overturns it to a state that prohibits the passage of pulses through a decade 4.2. Then, the input of the zero setting of this trigger comes a pulse from the output of generator 5 2 and overturns it to the opposite state, thereby setting decade 4.2 to the initial state. The work of the decade 4.4 and trigger 5.2 is similar. The output pulses of decade 4.6 arrive at the trigger synchronization input 5.4. When their temporary position coincides in phase with the constant "2 pulses arriving at input D of this trigger, it overturns and allows the passage of pulses from output 1" 4 of generator 2 through the coincidence circuit 6 to input D of trigger 5.3, to the synchronization input of which pulses from the output of the decade 4.5. With

the coincidence of the pulses arriving at the input

synchronization and input D trigger 5.3, it

tilts to a state prohibiting

passage of pulses through the decades 4.5, 4.6.

Then to the input of the installation of zero trigger 5.3

the impulse comes from the output of generator 1 2 and overturns the trigger in the opposite state, setting decades 4.5, 4.6 to the initial state. The time count after 24 hours is repeated automatically. Pulses from the outputs of phase-pulsed decades come to the display device 7, which is designed to visually read the time code in hours, minutes, and seconds.
