Abstract

Изобретение относитс к импульсной технике и может быть использовано в автоматике . Цель изобретени - расширение функциональных возможностей путем обеспечени генерировани двухпол рного выходного сигнала. В генератор, содержащий генератор 1 импульсов стабильной частоты, счетчики-делители 2,6 частоты, элементы НЕ 3,10, D-триггер 4, элементы ИЛИ 5,7,9,18, формирователь 13 импульсов, ключи 16,19,25, триггер 17, интегратор 20 и источник 24 опорного напр жени , введены D-триггер 11, элементы И 8,12,14,15, ключи 26,27. Длительность паузы между импульсами определ етс счетчиком-делителем 6, а длительность треугольного импульса - счетчиком-делителем 2, причем врем нарастани равно времени спада. D-триггер 11 в каждом следующем цикле через элементы И 8,12,14,15 измен ет пор док подачи на интегратор 20 положительного и отрицательного опорных напр жений с источника 24. Благодар этому на выходной шине 21 чередуютс положительные и отрицательные треугольные импульсы. 2 ил. сл сThe invention relates to a pulse technique and can be used in automation. The purpose of the invention is to enhance the functionality by providing the generation of a bipolar output signal. In the generator, containing the generator 1 pulse of a stable frequency, counters-dividers 2.6 frequency, elements NOT 3.10, D-flip-flop 4, elements OR 5,7,9,18, shaper 13 pulses, keys 16,19,25, the trigger 17, the integrator 20 and the source 24 of the reference voltage, the D-flip-flop 11, the elements AND 8,12,14,15, the keys 26,27 are introduced. The duration of the pause between pulses is determined by the counter-divider 6, and the duration of the triangular pulse is determined by the counter-divider 2, and the rise time is equal to the decay time. D-flip-flop 11 in each subsequent cycle through the elements AND 8,12,14,15 changes the order of supply to the integrator 20 positive and negative reference voltages from source 24. Due to this, positive and negative triangular pulses alternate on the output bus 21. 2 Il. cl
