Description

8 step voltage nerator, co-joint scheme 9, Straw shaper 10 (bim1pOcB, L1NIIB delay 11, forirovirovatel 12, quadrants 13 and 14, functional divider 15, phase degradation unit 16, idler 17, extraction unit 18, at 1H root, additional mixer 19 of the input signal and the on-board of the asynchronous generator of 2 strobe pulses, filter 20 and valve 21.

The control input of the valve 21 is connected to a Savshadan circuit, with the outputs of Kladans 4 | And 2: 1 Nvpo | Srvdstvve; H1no connected to the inputs of the functional divider 15 and through co, 13, 14 to the inputs of the adder 17.

The proposed device operates as follows.

The ash signal is adnovrvmanno supplied to mixers 1 and 19 and to the block. 5 zapuaka. The strobe pulse from the synchronous generator 2 of the pulse generator also goes to mixers 1 and 19, is delayed by the delay line 11, additionally to (emits 1c in Former 12 and pastels a coincidence circuit.

The generator | sawblock | raz1N01GO nap1r zhbN1 and begins to generate a sawtooth and delayed delay due to the delay of the signal in block 5 latch. From the output of the sawtooth voltage generator 6, the signal is fed to the comparison circuit 7, where the styrene voltage from the step voltage generator 8 is also supplied.

At the moment of coincidence of the voltages, the form | 10 | pulse generator starts with 10 strobe pulses, the M1pulse of which arrives at the circuit 9 of the coincidence circuit. During the coincidence of the strobe pulses of the formers 10 and 12, the coincidence circuit 9 outputs pulses to an 8-stage voltage generator for generating (not to the next stage voltage stage. At this moment, valves 4 and 21 pass the | | - x 1 and 19 in the form of low-frequency siphnals converted in filter 20 and divider p, asch | ir1 3. As the proposed device, generator 2 st |, M1pulses sends two strobes to mixers 1 and 19, modulated by BaiHHbix BsaiHiMHo By using these functions, for example, the one | H modulated by a sinw / type alarm and the other by cosco, then the output of the CLOB 4 and 21 is information proportional to the even and odd components of the “broken” point and the next signal. ,

that the spectrum of the modulated stationary | robot pulse coincides in the particular range with the studied one (signal O | M.

The transformed in frequency is even and odd components of a subsequent signal.

squares 13 and 14, are squared, and functional divider 15 to determine their ratio. The output signals from K1 quadratures 13 and 14 are fed to adder 17, from the output of which information about the energy spectrum of the signal goes to the recorder (electronic beam tube, self-wave, keynote tape, etc.) and to the square root extractor 18. At the output of the functional divider 15, an I1formation oi6 signal envelope is obtained, which is fed to the recorder.

The output information of the functional divider 15 is fed to the register and to the phase determining unit 16.

Thus, the proposed device determines the modulus and phases during strobe storage.

Fore M u l a and 3 o b e te e. I and

The device stroboscopic recording of repeated wide-band and; M1 pulses by aiBT. ov , characterized by

that, in order to determine the -module and phases in a stroboscopic conversion, two K1va1dritors were introduced, after the assembly, a functional divider and a phase determination unit connected in series to the adder and block to extract the square root, as well as serially connected additional input mixer and signal of neio1OrOnized strobe impulse generator, filter and valve controlling

the input of which is connected to the coincidence circuit, while the outputs of the valves are directly connected to the inputs of the functional divider and through corresponding quadrants to the inputs of the sum: mator.
