A disadvantage of the known device is relatively narrow bandwidth. The aim of the invention is to expand the dynamic range of the input signals with an increased number of signal multipliers.

Fig. 1 shows a functional diagram of the proposed multiplying device j in Fig. 2, a time diagram of signals. The diagram shows the first and second adders 1 and 2, the first and second integrators 3 and 4, the first and second relay elements 5 and 6, the pulse shaper 7, the amplitude modulator 8, the EQUALITY 9, the first, jth element, (j + 1) th, nth additional adders 10 ,, tOj, first, jth, ()th, nth additional integrators 11, first, jth, j.) --Th, 1 - th additional formers 12,, 12, 12 | 4,, 12 pulses, first, jth, (j + 15th, nth additional amplitude modulators 13 ,, 13 ;, 13j4i, 13 ", first, j- th, (jf1) th, nth additional relay elements U ,, 14, 14jv, 14, first, (JtO th, nth additional element S UNEQUALITY 15: ,, 15 p 15, inputs 16 and 17 of the first and second signal-factors, inputs 18, 18, 18ju, 18 n additional signal-factors, output 19, Multiplied the device works in the following way. First and second relay elements 5 and 6 are made with non-inverted hysteresis loops and zero-level switching thresholds symmetric with respect to ± V. The pulse shaper 7 generates pulses of stable amplitude and short duration synchronously with the time module and the end of the pulse period at its input. - The output signal of the amplitude modulator 8 has a duration equal to the duration of the pulses at the output of the pulse generator 7, and an amplitude proportional to the output level of the second integrator 4. The sign of the signal at the output of the EQUALITY 9 element corresponds to the sign of the product of the signals at its inputs. input 16, the output signal of the first integrator 3 is in the form of a symmetrical saw with amplitude te, and the output signal of the first relay element 5 is bipolar pulses of type m PDRA GO srednSh4 zero. The presence of a signal at input 16 leads to a change in the inclination of the saw-tooth voltage at the output of the first 3V integrator. One of the half-periods of self-oscillations is the growth rate of the saw-tooth voltage (Fig.2 ") determined by the difference of the signals at the input of the first adder t, and in the other half-period by the sum these signals. As a result, the self-oscillation period increases, the constant component of the output of the perforated relay element 5 reaches a level proportional to the signal at the input 16. The shaper of 7 hectare pulses forms a short-duration pulse (FIG. 2 6 which undergoes amplitude module MOAyjratope B) at the level of the output signal of the second integrator 4 (d.2 b). Switching the second relay element 6 is carried out by Short # 1 pulses (Fig. 2-8), the amplitude of KOTOI IX is not less than its switching thresholds. As a result, the edges of the signal (Fig .2) coincide with the time points of the change of the pulse sign (Fig. 2o (), which increases the accuracy of the operation. In order to multiply several signal multipliers, additional width-frequency-pulse modulators are functioning, formed by the j-th additional adder 10J, additional integrator 11., shaper 12: pulse, amplitude modulator 13; and relay element 14.; The operation of such a pulse width-frequency modulator is similar to the work of a pulse width-frequency modulator formed by second sums torus 2 and the integrator 4, amplitudn1m modulator 8, a second switching element 6 and the pulse generator 7. Synchronization of subsequent pulse-width-frequency modulators with signals from the output of the corresponding EQUIDITY 15 allows the bandwidth to be expanded, since the frequency of the pulses at the output of EQUALITY 15 (figure 2 g) is the result of the overlapping of the signals (figure 2.01 and e This allows an increase in the frequency of the pulses at the output of the fop in the pulse generator 12j (Fig. 2d). As a result, the frequency of self-oscillations (bandwidth) of additional frequency-width-1 pulse modulators also increases, since the resolution pulses the switching of the additional relay element 14- (Fig. 2e) is followed with a frequency proportional to the frequency of the output signals of the first and second relay elements 5 and 6. In contrast to the known device, the synchronization of each formed pulse-width-pulsed modulator (with the exception of the second) is proposed It does not occur in the function of the signal, which reflects the value of the previous co-occupant, but in the function of the signal proportional to the product of the previous multiplier signals. This makes it possible to increase the frequency of self-oscillations of subsequent modulators, i.e. to expand the bandwidth of the multiplying device. S Thus image 1, the proposed multiplying device, as compared with the known one, has a wider dynamic input signal range with an increased number of signal multipliers.
