FIELD: devices for interface between analog and digital signals. SUBSTANCE: serial circuit of high-frequency digital filter and digital integrator are introduced to accomplish the goal of invention. Input of digital filter is connected to direct output of flip-flop, direct input of comparator serves as device input, output of digital integrator serves as device output. This results in possibility to compare output voltage of analog comparator to current level of input signal instead of earth potential. EFFECT: increased speed, increased precision. |
