The invention relates to amplifying devices with inversely pulsed signal conversion and can be used in analog computers.

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

- FIG. 1 shows a functional diagram of a multi-zone deploying converter; in fig. 2 and 3 .- time diagrams of signals.

The converter contains generator 1 of triangular voltage, input 2, first and second adders 3 and 4, first, second, third, and nth key elements with dead band 5-1, 5-2, 5-3, ... 5 -n, exit 6.

FIG. 2, 3 P1 / TOTALS the following notation: x (t) is the signal at input 2; | | (t) is the output signal of the generator of the triangular voltage; (t) the output signal of the first adder 3), y (t), (t) is the output signals of the first adder 3 at different values of the signal at input 2; y (t) output signal 6; ± S.,, 1 S., ± - dead zones of the first, second and third key elements 5-1, 5-2 and 5-3, respectively

Multi-zone scan converter operates as follows.

At the output of the oscillator 1 of a triangular voltage, a signal is generated (Fig. 2q). the average value of which is zero. This signal acts on the input of the first adder 3.

In the initial state, with a zero value of the signal at the input 2, the dead zones of the key elements 5-1, 5-2, 5-3,.,., 5-n satisfy the condition:

1c; 1 (2j-l) i, where i 1, 2, 3, ... , P;

 C | - dead zone of the first key element

As a result, with a zero signal at input 2, the output signal of the generator

The first triangular voltage finds-50 is connected to the second input of the pers inside the dead zone of the adder, the output of which of the joint key element with the dinene zone with the entrance of the first key nonsensitivity 5-1 (i.e. inside dead zone.

equals zero.

Under the action of the signal from input 2, the output signal of the first adder 3

shifts vertically.

At y (t) s., (The input signal is positive) (Fig. 3a), at the output of a key element with deadband 5-1, a unipolar pulse (Fig. 3 &) is generated, which goes to output 6. As the signal grows input 2 (Fig. 3i, signal y (t)), an increase in the duration of the unipolar pulse per

output 6 (Fig. 3). When the signal at input 2 is greater than C., the first key element with dead band 5-1 goes completely to the open state (Fig. 3,. First

modulation zone), and the output pulses are formed in the second modulation zone (Fig. 3, d) due to the periodic operation of the second key element with the dead band 5-2 (Fig. 3q, signal

y; (t).

Subsequently, with an increase in the signal at input 2, all key elements with the dead zone become consecutive in the state of a logical unit, and the output signal is formed in the corresponding modulation zone.
