Description

one

The invention relates to the field of radio electronics and can be used in automation, computing and digital measurement technology.

Scaling circuits on phase-impulse multistable elements (FIME) are known, which have a number of advantages as compared to a scaling device on binary elements, containing a clock generator, a synchronizer, OR logic circuits, a reference cell, and FIME. Their disadvantage is that the division ratio of each FIME and the support element is determined by the individual selection of the elements of the FIME capacitive storage ring.

The purpose of the invention is to improve the reliability of the conversion circuit at FIME, which has a trigger decade at the input.

This is achieved by using self-tuning memory elements on the FIME as a reference cell, the division factor of which is established by means of the triggering decade.

The invention is illustrated in the drawing, which shows a functional diagram of the device, where 1 is a time relay, 2 is a control device of multi-stable elements, 3 is a coincidence circuit, 4 are prohibition circuits, 5 is a trigger decade, 6 is a clock, 7 pulse counter

on FIME, 8 - self-tuning phase-pulse multi-stable memory cell, 9-counting self-tuning multi-resistant phase-pulse cell, 10 - gate, // - scaling circuit input, 12 - OR circuit, 13 - synchronizer.

The device works as follows. After turning on the power or before the start of the measurement cycle, the time relay 1 is activated.

the control devices of the multi-stable elements 2, as a result of which the coincidence circuits 3 are unlocked and the prohibition circuits 4 are locked. At the same time, the input of the trigger decade 5 through the first open coincidence circuit 3

pulses of the clock generator 6 of the counter are fed to FIME 7. The trigger decade output signals through the second open coincidence circuit 3 adjust the reference cell with self-tuning 8 to the division factor

trigger decade 5. The output signals of the reference cell 8 through the open coincidence circuit 3 of the control device of multi-stable elements 2 adjust the counting FIME 9 by the division ratio of the reference cell and

set them to zero. After the time relay 1 is turned off by the falling edge of the output signal, the trigger decade 5 through the gate 10 is reset to the zero state, and the inhibit patterns 4 are unlocked. The output signals from the input // of the enumeration circuit comeTo through the first open prohibition scheme 4 to the input of the trigger decade 5. Transmitting pulses from the triggering decade 5 through the second open prohibition scheme 4 are fed to the counter input to FIME 7.
