excitation of the four harmonics consists of the excitation winding J, the output windings 2 and 5, connected inversely to each other, the recording windings 4 and 5, connected inversely by the corresponding output windings, and two keys

on transistors 6 and 7, controlled by input / Y and X, respectively. The windings are wound on two toroidal cores 8 of magnetic material with a rectangular hysteresis loop, with the 2–5 windings having the same number of turns and connected to the writing voltage emulators 9 and 10 via dividing diodes //.

The output windings 2 and 3 are connected to the readout circuit 12 with a low input resistance through the summing resistors 13 and 14, and the excitation winding / to the sinusoidal excitation current generator 15. As the current from the generator 15 (continuously supplied to the excitation winding, then at the output windings 5 and 5 there is a read voltage 5 corresponding to the stored coefficient W. When the input signal X (X is the inverted value of the input signal X - 1) L / WLJClrlilU V OPS1-1 „PG1 L1 i i I-l closed the transistor 6 and open key ° transistor 7. SL Consequently, the readout signal will go to the readout circuit only from the output winding 2 and the output of the readout circuit will be a signal corresponding to, which is equal to 11715 W. If X is 1 (+ 1), then the switch is closed on the transistor 7 and the switch is open on the transistor 6, the read signal only comes from winding 3, and the output of the read circuit 2 o will be a signal corresponding to the value of -W, since windings 2 and 3 are turned on inversely. With open "switches" (X X 0), the read signal will not arrive at the read circuit 12. Thus, reading 25 from the adaptive element of the product X-W is realized, where X can be -1, 0, +1. Diodes 11 are positive voltage latching voltage. To change the stored coefficient, a generator 9 or 10 outputs a 30-pulse pulse recording voltage with an amplitude greater than that of the blocking voltage. In accordance with the inclusion of windings 2-5 and keys on transistors and 7 when accessing a write pulse from generator 9, the stored coefficient W will be incremented, where C is a proportionality factor depending on the write-voltage volt-second square 40 write pulses from the generator 10 AW -CX, where the input signal X can receive signals -1, 0, + 1. Thus, the keys on transistors 6 and 7 realize the recording and reading of information B by the adaptive element, in which the input control the signal can accept values -1, O, +1. In order to reduce the excitation current at the recording process with a recording pulse duration of several times smaller for the duration of the excitation current period, the recording pulse is applied at the moment when the instantaneous value of the excitation current is zero. A change in the stored coefficient can also be made by bipolar recording voltage pulses applied to output windings 2 and 3, while the need for 55 windings of the front 4 and 5 is no longer necessary, but switching keys must ensure the passage of recording pulses of positive and negative polarity. The invention allows to expand the logical capabilities of the adaptive element, to increase the reliability of its operation, since it eliminates the possibility of falsely recording information at the input control, a signal, for example, due to a change in the parameter of the magnetic cores from temperature, and a change in the amplitude of the sense current in a sufficiently large range modifies the output signal of the adaptive element, but does not violate the logic of its rotation, so it is possible to use cheap ferrite cores with low irregularity of the hysteresis loop and low good parameter stability. The keys in the output winding circuits allow voltage pulses to be used for recording, which greatly increases the linearity of the change in stored information and allows adjustment of the magnitude of the stored information increment by changing the amplitude 1 of the recording pulses. Keys that switch low-power read signal and write pulses can be implemented on simple transistor circuits, which makes it possible to effectively use the adaptive element in conjunction with various electronic computing devices. Subject of the Invention Magnetic storage adaptive element, containing a write pulse generator, a reading circuit, magvite cores , dividing diodes, resistors, output winding and record windings, in series with which the switching keys, connected to their own The inputs to the imperfect input signals, characterized in that, with an extension of the functionality, an excitation winding and a second output winding are additionally introduced in it, the end of the first recording winding and the beginning of the second recording winding are separated through dividing diodes. the first helirator of the recording impulses, the beginning of the first output winding and the end of the second output winding are connected to the output of the second write pulse generator, the first output winding is connected to the output of the first switching key, the second starting winding is connected to the output of the second switching key, the first output The windings and the beginning of the second output winding are connected via resistors to the input of the readout circuit.
