The drawing shows a structural electrical circuit of the proposed device.

A device for converting analog information contains an analog signal source 1, an input multiplexer 2, a control unit 3 "

| N elements 1) memory, output 'multiplexer 5> additional output multiplexer 6, η circuits 7, each consisting of time-voltage converter 8 and additional memory element 9, delay element 10, comparison unit 11 and key' 12.

The device works as follows.

Source 1 receives analog information in the form of a sequence of pulses, the amplitude and temporal position of which are determined by the conditions of propagation of radio waves on the selected path. The input multiplexer 2 produces the distribution of the input signal among the elements. The operation of the input multiplexer 2 is controlled by the control unit 3 · The output signal of each channel of the input multiplexer 2 is fed to the corresponding element 4.

The outputs of the elements And using the multiplexer 5 are alternately fed to the signal input of the key 12, and the inputs of the additional elements 9 are alternately connected to one of the inputs of block 11, to another input of which voltage values are proportional to the pulse delay in the previous cycle , from the output of the delay element 10, which produces a delay in the voltage value from the output of the additional output multiplexer 6 for a time equal to the duration of the device operation cycle. If the magnitude of the delay pulses in adjacent cycles coincide or differ slightly, the blocks 11 outputs the enabling signal to the control

the input of the key 12 and the voltage equal to the amplitude of the pulse under study, passes to the output of the device and can be registered. If the voltages, proportional to the pulse delays in adjacent cycles at the inputs of block 11, are significantly different, there is no permit signal at its output, these pulses are considered to be 10 msec and do not pass to the output of the circuit. Thus, taking into account the time delay of the pulses relative to the moment of switching the channel and comparing this delay with the previous cycle

15 allows you to select signals, the temporary position of which is constantly or slightly changed during one cycle.

Application of the proposed device *

This allows you to increase the accuracy of recording the amplitudes of useful signals, so. how taking into account the time parameters of received pulses makes it possible to compare their delays and

25 weed out irregular signals that are interferences.
