Description

This invention relates to an electronic calculator ELN device 1 and can be used in analog computers.

A separating device is known, comprising an integrator, a comparator, a square pulse generator / key t13.

However, the known device has a low accuracy of operation.

The closest to the proposed is a separating device containing an integrator, keys, an inverter, a comparator, a large-scale amplifier 2.

A disadvantage of this device is the relatively low accuracy of operation, due to the nonlinearity and instability of the integrator.

The purpose of the invention is to improve the accuracy of work.

For this purpose, a separating device containing a first key connected in series and an integrator, a second key, an inverter, a scale amplifier, the first comparator, the input of the first key is the divider signal input, a square pulse generator, a second comparator, a modulo two, a third key and differentiating units, the integrator output being connected to the input of a large-scale amplifier, the output of which is connected to the first inputs of the first and second comparators through the first differentiating unit; x are connected to the corresponding inputs of a modulo two adder, the output of which is the output of the device, the input of the second key is connected to the input of the third key and is the signal-divisible input; the output of the second key is connected to the second input of the first comparator through the second differentiating unit, the third output the key through the third differentiating unit is connected to the second input of the second comparator, the output of the generator of rectangular impulses is connected to the control inputs of the first and second keys, and through the inverter is connected to the control yuschim input of the third key and. Figure 1 shows the functional diagram of the proposed device; figure 2 - timing charts of his work. The device includes a generator of 1 rectangular pulses, an inverter 2, the first, second and third keys 3,4 and 5, the integrator 6, the first, second and third differentiating units 7.8 and 9, the large-scale amplifier 10, the first and second comparators 11 and 12 modulo two 13 input

signal divider 14, the input signal is separable 15, output 16,

The separating device operates as follows.

The voltage of the signal divider is supplied to the first key 3, which. controlled by a square wave generator 1. From the output of the primary key 3, square-wave pulses (.Fig.2, Ua,) f are removed, the amplitude of which corresponds to the voltage level of the divider signal.

Simultaneously, the second and third keys 4 and 5 receive a voltage signal-divisible, and the second key 4 is controlled from the generator 1 rectangular pulses directly, and the third key 5 through the invertor 2. The outputs of the second and third keys 4 and 5 are removed motor impulses (fig. 2, 114.5) whose amplitude corresponds to the level of the signal-to-divisible voltage.

As a result of the passage of rectangular pulses from the output of the first key 3 through the integrator b, a voltage is generated that varies in time exponentially

the law (Fig. Idj and 4 5)

The rectangular pulses from the output of the second key 4 arrive at the second differentiation unit 8, and from the output of the third key 5 - to the third differential block 9. At the outputs of the second and third differentiating blocks 8 and 9, voltages are generated from the rectangular pulses ( Fig. 2e, F, UB / UP} - From the output of the integrator b, the scale amplifier 10 is supplied to the first differentiating unit 7, at the output of which (when all the differentiating units are equal in time), the corresponding voltage is formed (Fig. 2i. , Uy).

During operation, four states of voltage-divider voltage are possible (J and signal-divisible U

Oh Oh and., Then

. The nature of the signal transformations in these cases is depicted in Figure 2 by the columns of the signal diagrams. From the outputs of the first and second differentiating units 7 and 8, signals (FIG. 2i, and Ug) arrive at the first comparator T-lf and, from the outputs of the first and third differentiating units 7 and 9, signals (FIG. 2A, U7, and) arrive at the second comparator 12. At the outputs of the first and second coharators 11 and 12, pulsed signals are formed (Fig. 2k., U; Yag- i - The pulsed signals arrive at the inputs of the modulo two 13, the output of which produces a periodic pulse signal, whose frequency twice the frequency of the generator 1 rectangular pulses.

The pulse duration is determined from the expression

.

where K is the scale factor of the amplifier 10;

and - the voltage of the signal-divider Ud, - the voltage of the signal-divisible; C is the time constant of the differential blocks; T - the period of the pulse generator 1.

Compared with the device-prototype, the proposed dividing device has a higher accuracy of operation, i.e. the result of the conversion does not depend on the parameters of the integrator 6.
