Description

The invention relates to the field of computer technology and can be used in devices for processing and storing digital information presented in radio pulse form. A two-frequency radio pulse trigger based on an oscillator with two coupled circuits 1) is known. A trigger is also known, consisting of two autogenerators with a connection between the circuits of the autogenerator 2. "-. The closest to the invention is a technical solution of known trigger devices according to their technical essence and achievable - Electrofact is a trigger circuit based on Inlinear contours 3. It contains two frequency spectra of two resonators, two detectors. In the circuit, the circuit outputs are connected to the detector inputs, respectively. The outputs of the detectors are cross-coupled in the control circuit of non-linear circuits. The operation of the circuit is performed by using one of the two nonlinear circuits under the influence of an input video pulse signal applied to the corresponding input to a high frequency signal. The disadvantage of such a circuit is low sensitivity both in terms of the high frequency signal, and in relation to the input pulses itself, since for stable non-linear circuit operation it is necessary to drop large amplitudes, control pulses. In addition, the high frequency information is not memorized in the circuit, because when the signal is turned off, zeroing occurs. The aim of the invention is to increase the sensitivity of the trigger on the high-frequency signal. The goal is achieved by the fact that a radio pulse trigger containing two resonant circuits, the outputs of which are connected respectively to the inputs of two detectors, the outputs of the detectors are connected to the outputs of the trigger, the trigger input is connected to the resonant inputs. Ontures, introducing two RF amplifiers, the first inputs of which are connected respectively to the outputs of the resonant circuits, the outputs of the RF amplifiers are connected to the input of the device, and the Boryo-frequency amplifiers are connected to the outputs of the detectors.

The drawing shows the function diagram of the proposed device ..

The proposed device contains a resonant circuits 1 and 2, detectors 3 and 4, radio frequency amplifiers 5 and 6..

The operation of the proposed device is as follows.

Amplification of the RF amplifiers 5 and 6 podbyr yts way that the total gain for the rings formed by the resonant circuit; 1 and Amplifier 5, as well as circuit 2 and amplifier b, would be greater than one in magnitude, i.e., self-excited oscillations are provided with frequencies

In an aeton trigger, when the supply voltage is applied, oscillations occur at frequencies W and WT. These oscillations are determined by internal fluctuation and shock excitation in circuits 1 and 2 when a supply pulse is turned on. From the outputs of circuits 1 and 2, oscillations are applied to the corresponding detectors 3 and 4, where they are detected. The voltage from the output of each detector 3 and 4 is applied to the gain control circuit, respectively, of the adjacent amplifier, b and 5. Under the influence of this voltage, the amplification of the corresponding amplifiers occurs. However, the variations are not the same and depend on the trigger parameters and on the initial conditions and at the time of switching on and at certain ratios between the gain parameters, transfer factors of the torsion bars 3 and 4, and damping of oscillatory circuits 1 and 2. shoulders and the establishment of a single-frequency trigger mode.

The trigger can be controlled by piping. a trigger that is in one of two states for bFe, a radio frequency signal of a different frequency — forced reversion or simultaneous feeding of radio frequency signals at one of the possible frequencies and a power pulse, i.e. the rigger is turned on in the presence of an external high-frequency signal. After the termination of the external action, the trigger remains in the state corresponding to the frequency of the signal of the external action. Technique - the economic advantage of the proposed device in comparison with the prototype is that the use of positive feedback at high frequency through flashing injected amplifiers allows to obtain high

sensitivity to the input RF signal and to carry out the memorization of the input frequency signals.

in the proposed device, the cross negative feedback is carried out through the detector, i.e. by low frequency. The process of suppressing oscillations of the neighboring frequency is carried out, for example,

0 by the offset of the operating point of the RF amplifier. Resonant circuits are not tied to the high-frequency frequency, so this scheme is simpler to configure and more technologically advanced.
