Description

The invention can be used when

construction of schemes of transport and industrial automation, computing and digital measuring equipment, digital information transfer, etc.

The schemes of multistable elements (MES) with phase-impulse presentation of information are known, for example, a K-stable trigger.

The disadvantage of such schemes is the substantial dependence of the number of components on the number of stable states / C.

The aim of the invention is to simplify the element and reduce its dependence on the number of stable states / C while maintaining the possibility of implementing the proposed MEA on integrated circuits.

This goal is achieved by the parallel union A of the MUE with the smaller and mutually simple numbers of stable states Kt (, 2, ..., A;), the outputs of which are connected to the output of the offered MUE through the coincidence circuit. Wherein

P KI ---- K; min y; TO.

The MEA scheme includes L groups of serially connected components, for example, universal multi-valued elements (it is possible to use magnetotransistor elements) and one coincidence circuit on L inputs with one output.

The scheme of the MCE is shown in the drawing, where for simplicity, MEAs consisting of magnetotransistor elements are shown.

The MEA has one setup input 1, which is connected to the setup inputs of all the LEMs 2-6 with Kg steady states. Outputs t-x MUE (, 2, ..., L) are connected to

the corresponding inputs of the coincidence circuit 7, the output of which 8 is the output of the MCE on K stable states. If we assume that one of the K values of the information x (x O, 1, 2, ..., K - 1) is set on a digital period containing 2K cycles of t (t, 2, 3, ..., 2K-1 , 2 K), t: o all 2K cycles are connected to the components of each of the L MEAs.

To the input 1 of the MES on To steady state information is fed in even cycles (2.4, ..., 2K), on the same cycles (2, 4, ..., 2K.) The information is presented at output 8 of the proposed MUE .

Considering that a smaller value of the cycle corresponds to a smaller value of information (cycle 2 - O, cycle 4-1, cycle 6-2, and so on cycle 2K- (K-1), the operation of the circuit can be represented as follows.

By input to input 1 of the value of the digit x (x 0, 1, 2 ... / C-1), all the t-e MEAs (2, 3, 4, 5, 6)

are set to a specific state corresponding to the digit x. At the same time, a signal appears at output 8. Then, under the influence of constant clock cycles, each i-th MEA starts working as described in known devices with the only difference that during the digital period it gives a signal gi times (gi K / Ki). Since Ki (, 2, 3 ... A) are mutually simple, in the scheme of coincidence 7 signals with ix of MUE at the same time in ts only once per digital period, and this will happen on the beat corresponding to the digit X applied to input 1. Since Each of the L MEAs is a controllable generator ring, the whole MEAE as a whole will consistently output at 8 output a clock signal corresponding to the signal x to

those lor until new value X comes to input 1
