To put it in two words, and with an order of 3% or less, 10 have five binary characters. Adding one diviac d. And expressing whether the value is positive or negative is only six characters.

It can be assumed that to represent the curves in evil: leptypical sounds, it is enough to have 20 QOO instantaneous intercourse in one session: from sound. To record these 20,000 values, 120,000 (6):) two-sided signs will be required, as out of order, from units (1) and zero (,, 0).

The use of l-agitio or optical sound from its translations is possible; it can be produced with known sources described in the literature, e, -1 ect 01 10 -10-tube converters and recipe 1X 1x in binary numbers, W.

These transducers are: southern, use directly with the initial sound after the.

The speed of alternation of current on tires should be, for example, from 100 to 2X) 000 per second.

Structurally, the capacitor capacitor 101st ycTpoiiCTBO is a package of SPs presso} atellitized. One side of each snap-in (code) sheet of paper and metallized through holes (points W, W .... Pcs. To this point; round electrodes of elementary capacitors (circles) are connected. These connections are necessary "Oh, the performers are cut off (cut off). On the other side of the sheet against the indicated metalloid electrodes, there are six electrodes of this sheet, which are connected to the output transformer T.,.

The main (code) sheets are folded in a stack and between them are stacked on the screen sheet n gasket.

After compression, pressure points: up to 50 kg-cm-in. The unit in the block is supported by a bolt: l1. In this case, the 1 st contact between the individual points („inaiklaMn) in the sheets turns out to be very reliable. Such a block can then be flooded with a compound and isolated from the influence of the external environment.

Record units „1 and bullet ,, 0 on sheets produced, as already indicated, with iomosh, new perforations.

Transformers are connected to the outside; side to the electrode l and the block tires.

Due to the static sweep system of I1: p-tilt and the static page turning system, a static, having no moving parts, memory arrangement is obtained; stpp, which allows you to get differently; speed, for example, from 100 to 200000 pulses per second, recorded on the sheets of the unit (1) and bullets (0) in the recording sequence. At the output, there are some rows of units and zeros of this type:

1100CO, 110101, 100110, 101

010010, 110111, 001100

They can be used by six pulses per group to reproduce the instantaneous values of the current curve.

To reproduce the elementary sound recorded on a CPC, a current source 4, a scanning system O, 7, a keyboard key 1, a transducer 8, an amplifier 9 and a speaker 10 are used (Fig. 1).

The system has a pulse sweep with a small number of links. schematically in FIG. 3,

Fig. 3 denotes: 7j — impulse transformers, the heart of which iKii is made of 13 mater 1 ala, possessing a gniteresis loop, in the shape of a blnson to a rectangular shape; A-transformer 11309.5-4 -

Р {х), Р (у}, P (z) are the distributors of current circuits, state 1; none of the relay chain (I are the distributor elements).

The current source 4 (Fig. 1) is a lamp source of current pulses, the frequency of which is determined by regulator 5 (Fig. 1). The frequency value can vary within predetermined limits, for example, from 100 to 200,000 Hz.

Frequency dividers Lh. (X, D (y). (D} divide the frequency in accordance with the number of capacitors in the KZU element. If the KZU sheet consists of, for example, 32 rows of 32 capacitors, and the number of sheets in the KZU element is 64, then the dividers should be divided into 32, 32, and 64. At the same time, the output will be divided; 1е1 1 the following frequency will be such that the scanning of the elements of the strings of the n sheets of the needle and the interlace.

From the divider DC / x) pulses arrive at the distributor P (x). These pulses follow each other: o with a frequency of 32 cycles (period) of source 4. The current pulses excite the transformer: T-, half a sweep as needed, the necessary changes; induction changes and Bceii hysteresisio1et.

From the case of DCH (emulsions and stop the distributor P (}, then follow each other with a period of 1024 cycles of source 4 (Fig. 1). These impulses excite transformer relays, which in turn, excite the lines of transformer grid one.

From the divider DCH (r pulses go to the distributor P (z). They follow each other with a period of: -: 65536 ticks of source 4 and excite 7Y relays that unlock trapsforl ator L. connection 1, and the electrodes of the sheets with the keys 7 (Fig. 1).

The system scanner — obdsh d. L all 200-500 elements of the recording of individual sounds. The number of transformers T- is equal to the number L ;; STV.

A keyboard can be built similarly to a keyboard 1 and 1, a typewriter, and the letters on a KOTOpoii are most convenient for quickly typing words and phrases.

The connection between the individual keys of the letters and the output keys of the CPD can be established on any system.

For a rough assessment of such a possibility, it can be said that if there are 30 keys (20 consonants and 10 vowels), they can short-circuit 200 keys, which allow 200 combinations of consonants with vowels to be invoked.

If it is necessary to reproduce the sound with pomon, with the combination of three or more clavines, an additional key combination is used.

In the keyboard, you can set up en1, a variety of keyboards for various purposes. For example, the key of the repeated dialed key, the key of the increment1, its key or the keypad is determined according to the law of sound, etc.

The communication circuit between the clave: contacts and the keys is shown in FIG. 4 (for unon; eni only 8 keys and 16 elementov // are shown), on KOTOpoii it is indicated: L ,,, 12.. ,, ,, I; j-contacts of one keys, L-l.
