(54) START-UP ELECTRONIC REGENERATOR

fixed frequencies, a switch of 16 frequencies, a decoder 17 of the quitouting zone, a driver of 18 Quantization zones, an additional coincidence circuit 19, an analyzer 20, an adder 21.

The proposed regenerator works as follows.

In the analysis mode of the start and code iBce packages, the regenerator nodes are in the initial table state.

At the output of the input device 1, a zero signal appears, which corresponds to the expected starting parcel or crushing. In this case, the cyclic trigger 2 is set to the starting state, by turning the inverter 10 to receive the input signal. From the output of the reference frequency block 8, a clock sequence enters the coincidence circuit 3, the frequency of which is many times higher than the transmission rate. This sequence passes through a preliminary divider 4 with a division factor of four, and starts the main divider 5, the capacitance of which corresponds to the duration of the elementary parcel o. During operation of the main divider 5, pulses acting on the decoder 17 and Then, the first pulse at the output of the decoder 17 appears. A signal forms in the former 18, the beginning of the first transmission zone, the end of which indicates the appearance of the second and The pulse on the decoder 17, which forms the beginning of the second zone, etc. With the preliminary 4 and main 5 dividers in the former 15, sequences of short pulses of fixed frequencies are formed, from which several required frequencies can be selected using the switch 16. As a result, at the output of the adder 21 during the time to, we obtain a sequence of clock pulses, the following frequency — which is variable in different zones of the transmission. This sequence is quantized in the quantization scheme 11 by the incoming signal from the inverter 10. Thus, the incoming starting signal in the form of variable frequency sample pulses goes to the integrator: 7. If the energy of the analyzed starting signal does not exceed the fixed the threshold set in the fixer 13, it is decided that the fragmentation was fixed. In this case, the fi-xator 13 issues a signal with which the cyclic trigger 2 is set to a stop position. If a fixed threshold is exceeded, i.e., a starting premise is accepted, the operation of the circuit continues. At the same time, from the first discharge in the distributor of cycle 6, trigger 9 receives a signal to begin receiving informational CODE parcels. The latter translates the 10 V inverter into its working position, as a result of which the input signals of the required polarity are connected to the quantization circuit 11.

Next, information parcels are registered using a driver 15, a switch 16, a decoder 17, a forwarder 18, a coincidence circuit 19, an adder 21, an AND quantization circuit and a phycator 13. After receiving the fifth information parcel, the cycle distributor 6 issues a signal About the start of the stop parcel to the analyzer 20, where the stop parcel arriving from the input device 1 is analyzed only in its Middle most stable zone. The integrator counter 12 calculates the energy of the stop send for the analyzed period of time. If the accumulated energy of the stop signal is more than a fixed threshold, then the latch 13 outputs a signal to the cyclic trigger 2 and sets it and the whole regenerator circuit to the initial stop state, and the regenerator is ready to receive the following combinations. The output signals of the regenerator are generated in the output device 14.
