The pulse widened device of photoelectric couplers When we need to widen the narrow pulse, the figured circuit can be adopted. With the figured parameters, the pulse whose width is 3μs can be widened as the pulse of 1.2ms, as there is the passive feedback of the resistor of 100kΩ, so the output signal UA is more stable.
