Description

The invention relates to technical cybernetics and can be used in the design of electronic devices and automatic machines for radar and sonar signals made on elements of analog computing technology.

A device containing an analog-to-digital converter, shift registers, a digital-to-analog converter, a division unit, adders fj is known.

However, the known device is structurally made difficult and does not reflect the use of normalization. sets of analog signals simultaneously. .

Closest to the invention is a device comprising a delay line, an analog adder, a threshold cell, a memory cell, keys, and a divider.

However, this device does not allow the normalization of a set of analog signals at a constant dynamic range of change of the normalized signals at the output.

The purpose of the invention is to provide simultaneous normalization of analog signals with a constant dynamic range of their change at the output of the device.

This goal is achieved in that an analog device for normalizing signals, containing a group of keys and a group of dividers, introduces an extremum occurrence indication block, the outputs of which are connected to the corresponding control inputs of the keys of the group, informational inputs of coders are combined with the corresponding inputs of the position indicating block by extreme events and the first

the inputs of the group dividers are the corresponding inputs of the device, the outputs of the group keys are combined and connected to the second inputs of the group dividers whose outputs are the corresponding outputs of the device.

The drawing shows a block diagram of the proposed device.

The device contains a block of 1 decree. About the occurrence of an extremum, a group of 2 keys 3 and a group of 4 dividers 5.

The device works as follows.

To the corresponding inputs of block 1 indicate the place of extremum, the information inputs of group 2 of keys 3 and the corresponding first inputs of dividers 5 of group 3 receive input analog signals. . On one or several outputs of block 1 for indicating the occurrence of an extremum, signals equal to one are set, which correspond to the tag / i inputs of the device, to which the input analog signals with a maximum amplitude are received. The block indicating the place of occurrence of an extremum can be constructed according to one and well-known schemes, presented and 3,

The signals, equal to one, open the corresponding keys 3 in group 2, and the input analog signals with the maximum amplitude value are fed to the combined inputs of dividers 5 of group 4, to the other inputs of which the analog signals from the corresponding inputs of the device are received.

I At the outputs of dividers 5 of group 4, a set of analog signals is obtained, normalized by the maximum value. Thus, at the output of the device, analog signals vary from zero to one.
