SU405181A1 - DEVICE FOR TRANSMISSION - PRINCIPLE OF QUASITROIC - Google Patents

Description

one

The invention relates to the field of telegraph communication, namely, devices for transmitting - receiving quasi-terrestrial signals, and can be used to transmit quasi-terrestrial signals via switched connecting lines.

A device for transmitting - receiving quasitronic signals is known, which contains a binary to quasitroic signal converter with a synchronous generator, and a serially connected detector and a regenerator with a synchronous generator at the reception.

The purpose of the invention is to reduce the distortion of signals transmitted over switched channels.

This is achieved by the fact that a binary to bi-pulse converter is switched on at the transmission input, and at the reception the output of the regenerator is connected to the input of the bi-pulse signal converter to binary signals.

FIG. 1 shows a block diagram of the proposed device; in fig. 2 - time diagram of his work.

The transmitting part of the device consists of a converter of 1 binary signals into bi-pulse signals, the input of which is connected to the input of the device, and the output through the converter 2 bi-pulse signals into quasi-tropic signals to the output of the device. Synchronizer 3 is connected to converters 1 and 2.

The receiving part consists of the detector 4, which is connected to the input of the synchronous generator 5

And through the regenerator 6 to the input of the converter 7 bi-pulse signals into binary signals. The output of the synchronizing generator 5 is connected to the regenerator 6 and the converter 7. The device operates as follows.

A random sequence of binary signals comes from the sources of messages to the input of the device (Fig. 2, a) and then to the converter 1 of binary signals to bi-pulse signals. Output

Converter 1 sequence of signals (Fig. 2, c) is fed to converter 2 of bi-pulse signals into quasi-tropic signals. Sync generator 3 transmits to the converter 1 frequency pulses 2F

(Fig. 2,6), and on the converter 2 - frequency pulses F (Fig. 2, d).

Converter 2 contains an output transformer circuit that provides coordination with the connecting line and the transmission of quasi-terrestrial signals.

In the receiving part, the sequence of quasitroich signals (Fig. 2, e) goes from the communication line through the input circuit, which cuts off the received signals, to detector 4, at the output of which signals are received in bi-pulse form (Fig. 2, e). The synchronous generator 5 uses bi-pulse signals for discrete adjustment. At the output of the clock generator 5 receive a narrow clock pulses (Fig. 2g), which are fed to the regenerator 6 and the converter 7 bi-pulse signals into binary signals. After gating at the output of the regenerator, two sequences of signals (Fig. 2, C, I) are received, which are fed to the inputs of the converter 7. At the output of the converter, binary signals (Fig. 2, K) are output to the output of the receiving part of the device.
