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.
