The invention relates to radio electronics and can be used in information processing systems about the ratio of input signals.

A device for comparing the magnitude of two electrical signals is known - a comparator, which is a typical element of electronic equipment. A disadvantage of the known device is that no more than two input signals are compared.

A device for determining an input signal with extreme magnitude from several input signals is known, comprising a block of comparators performed on operational amplifiers, the inputs of which are connected to the information inputs of the device, and the outputs are connected via disconnecting feedback circuits, and the form of overload indicators of operational amplifiers on neon gas discharge lamps, which give visual information about the extreme of the compared values of the input signals.

It is also known a device for determining an input signal of extreme magnitude from several input signals, comprising a comparators unit, the first inputs of which are connected to information inputs of the device, an information storage unit executed on a storage register, the information inputs of which are connected to the outputs of the comparison unit, and outputs information outputs of the device, a generator of linearly varying voltage, consisting of an integrating filter, the output of which is connected to the second inputs of the comparator a comparison unit, a two-pole reference voltage source, a switch alternately connecting the outputs of the reference voltage source to the input of the integrating filter, and a pulse generator whose output is connected to the zero input of the information storage unit, as well as a recording signal generation unit on the logical element OR The inputs of which are connected to the outputs of the comparators block, and the output - to the recording control input of the information storage unit.

A disadvantage of the known device is that, by comparing the values of the input signals, it gives information only about the maximum or minimum signal from the group of input signals and does not allow them to be arranged in a predetermined way (for example, descending or increasing).

The aim of the invention is to expand the functionality of the device by providing an arrangement of the values of the input signals in a predetermined order.

This goal is achieved by the fact that a device containing a block of comparators, the first inputs of which are connected to the information inputs of the device,

The drawing is a structural diagram of the proposed device.

The device for comparative analysis of the values of electrical signals contains

5 block 1 of comparators, the first inputs of which are connected to the information inputs of the device, the second inputs are combined and connected to the information output of the generator 2 linearly varying voltage 0, and the outputs of the comparators are connected to the corresponding inputs of block 3, generating a recording signal: information storage 4, the outputs of which are the information outputs of the device;

5 block 5 control records; block 6 write resolution; polling timer 7 and block 8 elements And, the first group of inputs of which is connected to the outputs of block 1 of comparators, the second group of inputs is connected to outputs of block 5 of the recording control and information inputs of block 6 of recording resolution, and group of outputs is connected with the corresponding inputs of block 4 of information storage. The outputs of block 4 are connected to the corresponding inputs of block 5 of the recording control. The clock output of the linearly varying voltage generator 2 is connected via the polling timer 7 to the zero input of the information storage unit 4, the recording control input of which is connected to the output of the recording resolution block 6. The control input of the start of block 6 is connected to the output of block 3 of the formation of the recording signal.

The device works as follows. When the value of any input signal becomes less than the voltage of the generator 2 of a linearly varying voltage, at the corresponding input of block 1 of the comparators, a single logic level is obtained. The recording signal generating unit 3 converts the positive edge of the signal of the corresponding output of the comparator unit 1 into a short pulse. In the case of permitted writing to the information storage unit 4, a pulse from the output of the recording signal generation unit 3 passes through the recording permission unit 6 to the recording control input of the information storage unit 4. In this case, information is recorded from the outputs of block 8 elements And in block 4 of information storage and a simultaneous shift of previously recorded information in it by one bit, counted from the input. The outputs of block 4 of information storage are connected to the inputs of block 5 of the recording control. If there is a single level at any output of the information storage unit 4, then a zero level is set at the corresponding output of the recording control unit 5, which prevents repeated recording of the unit level from the corresponding output of the 8 element block And into the information storage unit 4. When unit levels are recorded from all outputs of block 8 and block 4, all levels of block 5 of the recording control block are set to zero, which prevents pulses from block 3 from forming the recording signal through block 6 allowing recording to control input recording block 4 information storage. At the time of the reverse voltage, the generator 2 linearly varying voltage generates a voltage pulse at the clock output, which passes through an interrogation timer 7 to the zero input of the information storage unit 4 and causes the contents of its registers to be zeroed, which results in the recording of information in block 4 storage of information. The impulse from the clock output of the generator 2, the linearly varying voltage passes through the timer 7 of the poll only if

the time interval from the previous recording resolution in the information storage unit 4 to the current time is longer than the time interval of the polling timer 7. So on the time interval from the moment

0 prohibition of recording in the information storage unit 4 until the arrival of the zeroing pulse from the output of the polling timer 7 in each register of the information storage unit 4 contains a position code in which the 5th digit number with the unit level corresponds to the number of the corresponding input signal in some way ordered ( descending or ascending) a number of input signal values. This

The 0 interval indicates a single signal at the second output of the recording resolution block 6. The use of the proposed device allows to solve the problem of the arrangement of the values of electrical signals in
