The invention relates to radio engineering-iKe and can be used on the receiving equipment of communication systems.

The purpose of the invention is the expansion of functional capabilities due to the indication of N from M channels with extreme signal levels over N analysis cycles.

The drawing shows the structure on the electrical circuit of the channel display device with an extreme signal level.

The device contains the first trigger IB. generator 2 sawtooth for example, M, input element OR 3, second two-input element OR 4, element 5 h. delays 5 keys, comparators, second triggers, third triggers 9, -9d, first elements, And 10, Shd ,, the second elements And 11, - the second two-input elements AND-LI 12, -12. .

The device works as follows,

With simultaneous post-pulsing of pulses to the input of the initial installation and the input of cyclic pulses of the device, the triggers Ij 8, -8, and 9 -9 are set to the zero state,

The impulse from the trigger output 1 starts the generator 2, enters the other inputs of the AND 1 11-i 1m elements, whose inputs are supplied with single signals from the trigger outputs, and opens the keys. Different levels of voltage from the device inputs are received through the public keys 61-6; ,, to the inputs of the comparator OE, to the other inputs of which linearly varying voltage is supplied from the output of the generator 2 At the moment of equality of the voltage at the inputs of the comparators 7 in one or several circuits, the corresponding comparators 7 and formed short A pulse that sets the trigger (hera) 8 to a single state. In the case when two or more voltages at the inputs of the comparators 7 differ by an amount within their resolution, and several comparators 7 and triggers are triggered & triggers 8 are set in the zero state in lower order numbers from a single signal at trigger output 8 in a chain with a large serial number, since the other input is

8. 2

(set to O) trigger 8 in each previous circuit is connected via a two-input element OR 12 to another input and output of trigger 8 in each subsequent circuit.

The pulse from the output of trigger 8 through the element OR 3 sets the trigger 1 to the zero state, as a result of which the generator 2 returns to its original | Running state and through element 5, the delay time of which is equal to the maximum installation time of the triggers 8, -8 dI (through the elements OR .,) to the zero state, is fed to the second inputs of the elements And 10, -10, and a single signal from the output of the trigger 8 of the circuit with a maximum voltage through the element And 10 sets the trigger 9 of this circuit to one and as a result the zero signal with output element 11 and closes key 6 of this chain. At the second output of the trigger 6 of the circuit with a maximum voltage, a single signal appears. This completes the first cycle of the device,

With the arrival of the second and subsequent cyclic pulses at the input of the cyclic pulses of the device, it works as well as with the arrival of the first clock pulse, except that in each subsequent m act the shutdown (closing of key 6) of that channel, in which trigger 9, the channel number with the maximum voltage on each cycle indicates the pulse at the output of the element 10 and the potential at the output of the trigger 9 of the corresponding circuit, as a result, N sets the selection through M cycles of the device with maximum voltages ,.
