Description

one

The proposed device is self-referencing to code-pulse telephony systems} 1n - remote signaling, also for controlling and several automated objects connected to the control point of communication channels.

It is known to analyze the code-information device, the input circuit, the trigger and the edge detection circuit.

In the known device for receiving addressioio applications, the receiving part of the soil device is sequentially connected to each subscriber input, i.e. the analysis of information arriving at the subscriber input is not constant and the address application may be not accepted.

The proposed analyzing device for coding information differs from that in that it includes a counter, a prohibition and an integrator, and the input circuit is connected via a trigger to the edge detection circuit, the output of which is connected to the counter input, the outputs of which are connected via the prohibition to the integrator input circuit .

This can improve the reliability of the device.

The scheme of the proposed device codopulse pnformatsp represented in the drawing and contains the input circuit /, trigger 2,

2

circuit 3, edge detection, counter 4, prohibition 5 and 6 circuits. integrator 7. The device operates as follows. The signal pulses are fed to the input circuit 1, the output voltages from which are fed to the corresponding inputs of the trigger 2. The output pulses from the trigger are fed to the edge separation circuit 3. There is no one in the initial position in counter 4 and integrator 7. The P1 integrator is a reversible counter for / g bits, which returns to the initial state of the / and the parcels. prnchel If there are two pulses from the edge selection circuit 3 during the length of time (.2-f). equal to the duration of two terminals, then from the second discharge of counter 4, the unit will go to the first input of the scheme “prohibition, 5, and to the prohibiting input of scheme 6, the recording of the unit

in which the first input is permanently impacted.

At the end of the indicated segment BpeMefui, the counter 4 returns to its initial state, and from the circuit 5 to the forward input of the integrator 7, one pulse will be output.

If during the time interval 2m more than two pulses will be given from circuit 3, then from the third discharge of counter 4 a pulse will not reach the prohibiting input of circuit 5, if

less than two pulses, the plgnul will arrive

the prohibiting input of circuit 6. Then either from circuit 5 (in the first case) or from circuit 6 (in the second case) a pulse arrives at the second input of integrator 7 and returns it for one bit of time.

If in time L will be less than (mn) error, then output 8 of integrator 7 has a pulse, which means receipt of a request for service.

If the number of errors is greater than (t-), then after the time D expires, the integrator 7 will be cleared.

Subject invention

An analyzer of code-pulse information containing an input circuit, a trigger, and a frontalization circuit are characterized in that, in order to increase the reliability of the device, a counter, an interdiction circuit and an integrator are introduced into it, the input circuit is connected via a trigger to the frontal allocation circuit, output which is connected to the input of the counter, the outputs of which are connected through the "prohibition to the input of the integrator.
