The proposed selection relates to analog information transmission devices and can be used for analog and combined analogue systems. ...-- ..,

Known analog zanrminayuschee device s6do |) Zhaschee zapy nayushuyu capacitor cell connected through .Dr1og rows and hydrated with control keys povtOrptol, connected on entry through diods record key, and for the output r from the output of the reading circuit, and a circuit comparing the input and output signals connected via a write signal shaper to the input of the write key.

The proposed device contains an integrating capacitor connected to the input of the recording key, and the input of the repeater is connected via a non-linear element to the slab key diode.

By such an implementation, an increase in accuracy and speed is achieved.

The drawing shows the scheme of the proposed online storage device, where:

/ - comparison of input and output signals; 2 - recording signal shaper; 3 - integrating capacitor; 4 - write key; 5 - record key diode; 6 - nonlinear element (diode); 7 - capacitor memory. cell; 8 - key clearing; 9 - control key; } 0, .- diode gashI; .//, ./2 - Dery diodes, urraeleni; 13 - repeater; 14 - output circuit reading I ..,.

C / i, 6w1, U-J, {7fg, t / 1-ash, (Jc4 - respectively, designation of the input, output, write, control, quench and readout voltage of the locking device.;, F / C - signal

zapnsts; E - power source.

The recording of the signal in the storage capacitor cell 7 is carried out in the presence of control signals. F / ynp, n f / ynp2 i

f / m input signal other than zero | f./iis | -0, current / 3 flowing through the circuit: key 4, diode 5, nonlinear element 6, cell 7, diode // II key 9. Simultaneously with recording the signal in the circuit, it reads the signal Uypp (C / mc). The output signal is continuously compared in the comparison circuit with f / Bi. In case of equality, the shaper 2 forms the controlling ornnal closing the sainiroi 4 key, and, thus, the recording stops with some delay ts. When you disable the recording signal and. from the memory capacitor cell 7, the output signal 6out 1 proportional to it decreases as the

the voltages on the nonlinear element 6, the bottom 11, and the key 9 are zero if there is no write current 1h.

The repeater's input potential is equal to:

I / noBT f / e-ff / 7 + yil + f / 9, (1)

where f / G, Uj, (/ 11, (/ 9 - falls are strained on the elements 6, 7, //, 9, etc.), the current is low / 3.

(0 nrn gi 0. (2)

If the output signal is 6g, but the proportional signal to the memory cell prn / 3 0 is less than the input signal Lcx, then the recording process is repeated. The number of possible repetitions depends on the fulfillment of the condition ((after each clock cycle, the recording is either limited or underestimated by time.

A capacitor 3 is connected to the output of the imaging unit 2, the purpose of which is to delay the front edge of the switching on of the signal with a constant time longer than the delay time g in the feedback loop. It is obvious that the capacitor 3 should not have a significant effect on the delay in switching off the recording t. With which it increases, the error t-sanHCH increases.

The front of switching on the signal at the output of the 4-UZ record key is determined by the signal of generator 2 (prn 6z const1), therefore, has a character close to the exposure), and during the delayed time, the amplitude of the signal at the output of the key 4-f / s does not change ) ia is a small value (nrn bvyh bph), and by appropriate selection of the characteristic elements of the key span, the diode of the write key, the nonlinear element, the day of the control key and the control key H1, the recording is performed at a low current ia, which goes to every the test cycle recording.

A decrease in current at / at a level of f / iiux, close to IJ -.-., Causes a decrease in the recording accuracy at a certain POWERFUL delay for a delayed recording error.

The axial role in choosing the optimal

non-linear sum.marginality) ist 11K11 -: jnementov (J, 11 and 9, which is 100% of the full-line terminal (/ doo, summed with the signal of the storage co-sensory cell and uninterrupted through the newtor 13 and the output read by the output device, and the input of the comparison circuit 1, plays the characteristic of element 6, since the element // and the key 9 have a certain

the functional assignment, namely: the diode // together with the diodes 5, 10, 12 constitutes a compensation bridge circuit, and with the help of the key 9, the memory capacitor cell is sampled at 5 written and sequenced. It is possible to include nonlinear element 6 at any place in the sequential value - repeater input, memory cell, accumulator 7, diode //, HIH is at zero potential, since the assignment

 element 6 is the addition of some additional signal / 7dog to the signal of the storage cell, which is done when the element 6 is turned on. When the matrix device is built, it is optimal to turn on the linear element 6 next to the diode 11, since this element becomes common for several tires in the corresponding line.
