Description

The invention relates to radio. electronics and can be used in information processing devices, in particular in network interference analyzers, anomalous peak recorders in electroencephalograms, cardiograms, etc.

The aim of the invention is to increase the reliability of the received signals. ·

The drawing shows a structural diagram of a device.

The device has information inputs 1 <- 1c, communication channel 2, signal selectors (3 <- 3c) of the signal, elements 4c and 5 ₍ - 5c) of the ban, counters 6 _to 6 _M , decoders 7 _l - 7 c , multivibrators 84 8c, inverters 9 4 - 9 _N , high-pass filters U4 10c, integrators 114 - 11c, threshold elements 12 ^ 12 c, shapers 13 4 - 13 c and 14 ^ 14 N pulses, recording unit 15, reference bus 16 voltage.

The device operates as follows. -

Information signals are amplified and fed through the communication channel to the input of signal selectors З4 - Зц of the signal, which select signals for duration. The signal selectors are piezoelectric resonators. When signals arrive at them, oscillations are excited in them, following the incoming signal. The first elements of the prohibition pass the adjusted (set) number of vibration peaks, which implements the mode of multiple reflections from the cavity walls, which are fixed by the corresponding 6-4 - 6 L counters and are entered into the block of 15 counters through the corresponding decoder 7 4 - 7c. After fixing the last of the given number of peaks, the corresponding standby multivibrator 8 ₄ - 8nj generates a control signal that, through the corresponding inverter 9 ₄ - 9c, is supplied to the second inputs of the second elements 54 - 5c of the ban and through the formers 134 -13c to the inputs of zeroing the counters 64 - 6c . Moreover, on the second elements 5 4 - 5c prohibition. . the damping signals are generated in the 3 4 - Зц selectors and the neutralization of high-frequency Barkhausen noise, the outputs of the З4 - Зц selectors are connected to the inputs of the high-frequency filters 10, 10c.

The signal from the output of the 3 _x -Zz selectors is fed to the input of high-frequency filters 104-10ts, then to the integrators 11 ₍ -11 _N and then to the input of the corresponding threshold elements 12 ₄ 12ts. Here, a comparison is made with a given level of the reference voltage that is supplied from the bus the reference voltage, and if the signal from the integrator is greater than the reference voltage, the threshold elements 124 - 12c generate the signal of the corresponding waiting multivibrator 2. The second formers 14 4 - 14c return the integrators to their initial state 11 4 - 11 _ϊ ϊ

The device increases the reliability of the received signals due to the control of a given number of vibration peaks excited in the signal selectors, as well as due to the possibility of controlling the duration of the oscillatory process of spurious shock oscillations and eliminating the destabilizing effect of Barkhausen jumps.

Piezoelectric resonators are used as selectors of 3 ^ - 3s signals. The shapers 13 <- 13c and 144 - 14c of the pulse are a differentiating circuit.
