Недостатком известных устронств вгг этс то, что в р де случаев наличие корреК1Нру;;;Щ51{ цепочки оказываетс недостатошым дл ггодаБлею1 импульса помех и устранени ложного считьшашш, иНизклй порог срабатывани сснспного транзистора и налтше положи ге.ьнпГ; обратной св зи обуславливают высокую чувствитепыюсть к помехам, которые имеют место з .многоканальных системах. A disadvantage of the known devices is that, in a number of cases, the presence of a corrector is insufficient for the year of an impulse of interference and the elimination of a false balance, and the low threshold of the response of the transistor and the situation; Feedbacks cause a high sensitivity to interference that occurs in multi-channel systems.

Claims

Claim

The additional transistor 9 is controlled by a blocking signal supplied by / la ero4iazu. At the time of recording and the storage time of the recorded information, the blocking signal has a level sufficient to maintain the transistor 9 in a saturated state. Therefore, all the interference on the basis of the transistor 5, both during recording and the read commands induced on the circuit, are bridged by an open collector-emitter junction of the transistor 9, the voltage drop on which in the saturation state can be only tens of mV, which is much less than the opening voltage of the transistor 5 of hundreds of mV. By the time of reading the information, the blocking signal is removed, that is, its level is close to the potential of the common bus, so that the transistor 9 closes. The resistance of the collector-emitter junction of the transistor 9 in this case is large and amounts to hundreds of ohms. This is much more than an analog storage device containing a ferromagnetic core with record and read windings located on it. the feedback winding, which is connected through the resistor to the base of the main transistor and to the control bus, the collector of the main transistor is connected to the end of the read winding, the beginning of which is connected to the power bus, the emitter of the main transistor is connected to the zero potential bus, and the lock signal bus, characterized in that, in order to increase the noise immunity of the device, an additional transistor is introduced into it, the collector of which is connected to the base of the main transistor, the emitter of the additional transistor is connected en with the tire ground potential, and the base - with the bus lock signal 30.
