FIELD: pulse devices. SUBSTANCE: device has clock oscillator 1, integrator 2, reference voltage power supply 3, comparator 4, flip-flop 5, subtracter 6, integrators 7 and 8. Reference voltage power supply 3, integrator 7 and 8 and subtracter 6 are connected to serial circuit. Second input of subtracter 6 is connected to output of integrator 7 and its output is connected to one input of comparator 4, which another input is connected to output of integrator 2 and which output is connected to one-setting input of flip-flop 5 which output is connected to output line and which resetting input is connected to output of clock oscillator and reset inputs of all integrators. Input of integrator 2 is connected to input line. Device provides modulation by means of conversion frequency to time interval. Device may be used in power supply units and static systems of automatic control. EFFECT: increased field of application. |
