The generator 2 produces a pr mo30

coal pulses, which sets the frequency of information pulses in the frame (cycle). Counter 3 converts the sequence number of pulses coming from generator 2 into a binary code, which is decrypted further by decoder 4 so that a high (low) voltage level is present at only one of its outputs, corresponding to the binary number at its first inputs. the decoder input. 4 is used to form the duration of its output pulses, equal to the duration of the pulses generated by the generator 2. The block 5 of the PWM modulators is used to modulate the pulses from each output of the decoder 4, PWM modulator also performs the function of pulse forming frame synchronization which exceed the duration of one clock time.

in which is determined by the binary number on the weekend halls; imam for each channel and is proportional to the number of channels,

The D inputs of the first channel flip-flops are connected to the corresponding D-BXOs of the second channel flip-flops, etc., the D-ones connected in this way are the first inputs, and the C inputs of each channel are connected in parallel by the second inputs of memory ti.

Information is sent to the D-inputs at the same time, but is recorded on the channel for which the C-inputs of the D-flip-flops are given a pulse.

The device works as follows.

On the transmitting side 1, the generator 2 generates rectangular w pulses, which are considered to be counter 3 and f0p 1 sequentially at the outputs of the decoder 4, and the number of outputs of the decoder 4 determines the number of 50 channels, and several free last outputs for generating a pulse frame synchronization. The pulses from each output of the decoder 4 are modulated in width by a block.

synchronization pulses are formed from

signals from the last outputs of the decoder-55 5 PWM modulators, after which the arching of the four.

The receiver 10 at the receiving side 9 serves to receive, amplify and correct the distorted lines in the communication line. The generator 11 generates short pulses of a higher frequency than the generator 2, and determines the digit code digit at the outputs 19 of the device. Element And 12 performs a logical log of a match function. Counter 13 converts the pore rfc pulse number, postgame Ix at its first input, into a binary code and is reset to 0 when the 1st km-pulse is fed to the second input. Shapes 14 and 15 pulses form short pulses through the cut of the input signal. The counter 16 performs the same function as the counter 13. The decoder M on the receiving side 9 performs the same function as the decoder 4 on the D-trigger triggers such as the latch, the quantizing side 1, the Memory block 18 is

At the receiving side 9, with the aid of the receiver 10, the received signal is amplified and brought to the same form as at the output of the element OR 6.

The first width modulated pulse from the output of the receiver 10 opens the element AND 12, the counter 13 is filled with g: Pulse; : m produced by generator 11, i.e. At the outputs of the counter 13, a combination of high and low voltage levels is formed, corresponding to a 4ncnoBONfy width of the first pulse width modulated. At the end of this pulse, a short slice pulse is generated by the pulse shaper 15, which with the help of a counter 16 and a decoder 17 is allocated at the second output of this decoder and fed to the C inputs of that D-flip-flop group in memory block 18, which is from It is carried to the first channel.
