FIELD: radio engineering.SUBSTANCE: invention relates to radio engineering and serves for analogue alternating-sign signals converting into rectangular pulses. Device consists of three comparators, three triggers and logical element “AND”. of First comparator output is connected to D-trigger clock input, which D-input is logical unit fixed level input, second comparator output is connected to first and second RS-triggers resetting inputs, first RS-trigger setting input is connected to third comparator output, which direct input is connected to device input, second RS-trigger setting input is connected to “AND” element output. First input of which is connected to first RS-trigger output, and second input is connected with first comparator inverting output, second RS-trigger output is connected with D-trigger resetting input. First comparator inverting input is first threshold voltage input, third comparator inverting input is second threshold voltage input, second comparator direct input is third threshold voltage input.EFFECT: technical result consists in producing undistorted duration pulses in absence of interferences and reduction of pulses distortions in presence of interferences, since device provides absence of hysteresis characteristic.3 cl, 3 dwg |
