FIELD: devices for modeling signals. SUBSTANCE: device has clock 1, four waiting multivibrators 2-1, 2-4, adder 3, noise oscillator 4, pulse counter 5, gate 6, four pulse shapers 7-1, 7-4, controlled delay gate 8, three low-pass filters 9-1, 9-3, two amplitude modulators 10-1, 10-2, sine-shaped signals oscillator 11, two band- pass filters 12-1, 12-2, unit 13 for computing normalized distance between reflecting layers, phase shifter 14, two Schmidt flip-flops 17-1, 17-2, AND gate 18, pulse generator 18, two memory read-write gates 20-1, 20-2, two analog-to-digital converters 21-2, 21-2, frequency meter 22. Device provides possibility to estimate normalized distance between reflecting layers. Computed distance is weighted by difference in relative amplitudes of resulting signal. EFFECT: increased functional capabilities. 4 dwg
